Q: What is a turritella?
from Lauren P., Vancouver, Washington, United States; May 30, 2000

A: The Turritellidae are a family of snails (also called Screw snails and Auger snails) that live on the sea floor and eat plant detritus. These gastropods have a long, conical, spiral shell and a circular aperture. They evolved during the Permian period. The genus Turatella was named by Lamark in 1799 and has hundreds of living species.



Q: Is it wrong if I wish to call a dinosaur name without "us" as a suffix? (Like "Carnotaur" instead of "Carnotaurus" and the purpurse of using it if without "us").
from Thomas K., ?, ?, ?; May 30, 2000

A: It changes the meaning. The name with the "us" at the end indicates the individual genus; the name without the "us" usually indicates a larger group. For example, Stegosaurus refers to all the species within the genus Stegosaurus; stegosaur (or stegosaurid or stegosauria) refers to all the stegosaurs, like Stegosaurus, Kentrosaurus, etc.

from Jamie B., holmdel, New Jersey, United States; May 30, 2000

Q: Was T-Rex a scavenger or a predator? Do you have any information that would help me? Thank you!!
from Craig W., Holmdel, New Jersey, United States; May 30, 2000

A: Most paleontologists think T. rex was a hunter, but Jack Horner (and others) think he was primarily a scavenger. For more on this debate, click here.



Q: I want to know about the adaptation of a woolymamoth?
from Dynamic D., Bpt., Ct., U.S.ofA.; May 30, 2000

A: Some of the obvious adaptations of the Woolly Mammoth to its cold, snowy environment were is long hair (which insulated its body and kept it warm), its long tusks (which it used to get food through the snow and ice, and also may have been used as protection), its small ears (which minimixed heat loss), and its relatively large size (which also minimized heat loss). For more information on the Woolly Mammoth, click here.

from Jawid K, suffolk, New York; May 29, 2000

A: Chasmosaurus was a ceratopsian dinosaur; it was a three horned, plant-eating, frilled ceratopsian dinosaur that lived late in the late Cretaceous period, about 76 to 70 million years ago. It was 16-26 feet (5-8 m) long and weighed about 3.5 tons (3220 kg)s. For more information on Chasmosaurus, click here.



Q: What are thecodonts? I am not familiar with this term could you please help me find a definition and information on then please.
from jack k, quebec, ontario, canada; May 29, 2000

ChasmatosaurusA: Thecodonts were socket-toothed reptiles, Triassic period archosaurs that mat have been the ancestors of dinosaurs, birds, pterosaurs, and crocodilians. The archosaurs are divided into the thecodonts, crocodylians, pterosaurs, and dinosaur (plus birds).

A: Diplodocus had the longest tail. It was up to 43 feet (13 m) long.



Q: Looking for information on a certain dinosaur called "Goyocephale"
from ?, ?, ?, ?; May 29, 2000

A: (pronounced GOH-yoh-SEF-ah-lee ) Goyocephale (meaning "elegant or decorated head") was a thick-skulled, flat-headed, plant-eating dinosaur with knobs and spikes on its pitted skull and large teeth. It dates from the late Cretaceous period, about 85 to 80 million years ago. This homalocephalid pachycephalosaur was found in Mongolia (the skull and parts of the skeleton were found). Goyocephale was named by Perle, Maryanska and Osmolska in 1982. The type species is G. lattimore.



Q: What does the word "Paleontologist" mean.
from Kerryn M, Inverloch, Victoria, Australia; May 27, 2000

A: A paleontologist is a scientist who studies paleontology, the forms of life that existed in former geologic periods, chiefly by studying fossils. "Paleo" means old or ancient. "Ontology" is the study of existence ("onto-" means existence, "-logy" is the study of something). This "-ist" at the end means a person who is involved in the field.



Q: What does a Ceratops dinosaur look like?
from Verna R., Big Spring, TX, U.S.A.; May 28, 2000

Q: I am in 10th grade and I have to get three-five proofs of how dinosaurs evoled from the eoraptor. please please help me. I went to your site where it shows how dinosaurs evoled but wasn't able to get much help:) thank you:)
from jessica z, ottawa, ontario, canada; May 28, 2000

A: Eoraptor was probably a side branch of the cladistic dinosaur tree, but its close ancestors may have given rise to many theropods (but the ornithischians evolved from another branch entirely). The oldest-known dinosaurs so far are two 230 million year old prosauropods from Madagascar, which may have (or their ancestors may have) given rise to sauropods. You can look at characteristics of these early dinosaurs and trace the development (evolution) of these characteristics (like tooth structure, hip structure, leg length, number of digits, etc.) in later models. For a list of early dinosaurs, click here.



Q: What is the oldest dinosaur that lived in the triassic period?
from David and Tyler, Roanoke, VA, USA; May 28, 2000

A: The oldest-known dinosaurs so far are two 230 million year old prosauropods from Madagascar.



Q: How big is the Oviraptor and what speed did it move.
from Aaron, Rancho Cucamonga, California, U. S. A.; May 28, 2000

A: Oviraptor was about 6 to 8 feet long (1.8 to 2.5 m) and weighed roughly 55 to 76 pounds (25 to 35 kg). It was a fast, agile dinosaur, perhaps running about as quickly as an ostrich, which can run up to 43 mph (70 kph). For more information on Oviraptor, click here.



Q: wher there any dinosuars in the state of florida and if so were?
from dave g, largo, florida, usa; May 28, 2000

Q: What do crabs eat?
from Heather D, East Kingston, New Hampshire, America; May 28, 2000

A: There are almost 5,000 different species of crabs, and thier diets vary extensively. Many crabs are omnivores (plant- and meat-eaters), others are carnivores (meat-eaters), and some are herbivores (plant-eaters). For more information on crabs, click here.



Q: If dinosaurs and other prehestoric creatures, like ptearosaurs, marine reptiles, mamoths, saber-tooth cats, and giant sharks and crocodiles were alive today, what would the earth be like?
from Phillip S, Sterling, Illinois, United States; May 27, 2000

A: The Earth would be incredibly crowded and diverse!. Paleontologists estimate that over 99% of the species that ever lived have gone extinct. That means that if all the extinct creatures were still alive, there might be well over 1,000 times as many species of organisms on the Earth.



Q: What is the name of the large carnivore with the spikes on its head from the movie Dinosaurs? Was it bigger than t-rex?
from pierson c, vancouver, WA, usa; May 27, 2000

Q: Do the dinosaurs with the long necks, have two brains? One in the head and one in the tail.
from Andrew B, Rocklin, CA, United States; May 25, 2000

A: Probably not. It used to be thought hat they did, but paleontologists now think that what they thought was a second brain was just an enlargement in the spinal cord in the hip area. This enlargement was larger than the animal's tiny brain..

Q: what did the juassic period look like? AKA vegetation, terrian.
from ?, ?, ?, ?; May 25, 2000

A: During the Jurassic period the environment varied from place to place. Some places were wet, others were dry, some were very warm, some were colder. On the whole, the Jurassic was warmer than it is now. As for plants, flowering plants hadn't evolved yet, so many of the plants that dominate the Earth today (like grasses) weren't around. For a page on Jurassic period plants, click here.



Q: I want to teach my 2nd grade class about the astrodon. I have found some information but not much. I am confused to whether or not the astrodon is actually considered a dinosaur or not. I have found information stating that it was not considered a dinosaur and information stating it was a dinosaur. I want to be able to give my class the correct information since we live in Maryland and this will be of great interest to them.
from Janet G., Baltimore, Maryland, USA; May 25, 2000

A: Astrodon (meaning "star-tooth") was a long-necked plant-eating dinosaur, a brachiosaurid sauropod that was about 30? feet (9 m) long (which is small for a brachiosaurid). It lived during the early Cretaceous period, about 130 million-120 million years ago. Astrodon is known only from fossilized teeth found in Maryland, USA (Astrodon is the state dinosaur of Maryland). Astrodon was named by Johnston in 1859. The type species is A. johnstoni. Astrodon may be the same as Pleurocoelus.



Q: According to all of my paleontology books paleontologists say there was no dinosaur that ever flew is that true? Also, what is the most interesting and completed dinosaur besides sue the T-Rex?
from Laura G., El Paso, Texas, United States; May 25, 2000

A: That's true, no dinosaurs flew. There were flying reptiles that lived during the time of the dinosaurs, called pterosaurs. Some pterosaurs included Pteranodon, Pterodactylus, Rhamphorhynchus, and Quetzalcoatlus.



Q: Someting about dinosaurius?
from TYYU, M, TN, TYJK; May 25, 2000

A: I've never heard of Dinosaurius. Dinosaurus, however, was a large, plant-eating dinosaur (a plateosaurid prosauropod ) that lived during the late Triassic period in what is now Europe. Dinosaurus was named by Ruetimeyer in 1856. Dinosaurus (later Gresslyosaurus) is probably the same as the genus Plateosaurus.



Q: why does some dinosaurs have long necks?
from ?, ?, ?, ?; May 25, 2000

A: It was probably an adaptation to get food. Some dinosaurs, like Brachiosaurus, had a giraffe-like stance, and they likely used their neck to reach leaves high in trees. Others, like Diplodocus, couldn't lift their necks high, but may have used their neck to reach into water to get soft aquaic plants or into thickly-forested areas.



Q: Is there a fossil as big as the T-Rex
from Nicole W., Traverse City, Michigan 49684, USA; May 25, 2000

A: Yes, many dinosaurs were bigger than T. rex. Two other meat-eaters were slightly taller than T. rex (Carcharodontosaurus and Giganotosaurus). Many plant-eaters (like Argentinosaurus, Diplodocus, Seismosaurus, and Brachiosaurus) were MUCH bigger than T. rex.

A: Click here for the first dinosaur discoveries.



Q: WHAT THE DIFFERENCE BETWEEN THE TYRANOSAUR REX AND TYRANOSAUR ?
from ?, ?, ?, ?; May 25, 2000

A: Tyrannosaurus rex was a type of tyrannosaur (also called tyrannosaurids). Tyrannosaurids were meat-eating dinosaurs (theropods) with two-fingered hands, small arms, a large head, sharp teeth, and lond, powerful hind legs. They lived during the late Cretaceous period. Other tyrannosaurids included Albertosaurus, Alectrosaurus, Alioramus, Chingkankousaurus, Daspletosaurus, Gorgosaurus, Nanotyrannus, Prodeinodon, Tarbosaurus, and T. rex.



Q: How many rows wide is stegosaurus plates
from ?, ?, Indian, usa; May 25, 2000

A: Paleontologists think that Stegosaurus' plates were arranged in two rows running along the back and upper portion of the tail. Since the plates weren't attached to the vertebrae, the positioning of the plates is not entirely certain.



Q: what kind of sound did the dinosaurs make?
from Brendan W., Madbury, NH, USA; May 25, 2000

A: Diffeent dinosaurs probably made very different sounds - some may not have made sounds. One dinosaur, Parasaurolophus, had a large, resonating hollow bony crest on its head, and paleontologists think that it was used to make a low, trombone-like sound.



Q: How many types of dinosaurs were there
from BOB R, ?, ?, ?; May 25, 2000

A: About a thousand genera have been found, but many, many more existed.

Q: What you know about Histriosaurus boscarollii, a new dinosaur discovered by Dalla Vecchia? I work on the movie about istrian outcrop of dinosaurs, so I need this information as quickly as possible! Thank you.
from David P, Pula, Croatia, Croatia; May 24, 2000

HistriasaurusA: (pronounced HIS-tree-ah-SAWR-us) Histriasaurus (meaning "Istrian lizard," for the Istrian peninsula of northwest Croatia, on the Adriatic Coast) was a large plant-eating dinosaur that lived during the early Cretaceous period (from the late Hauterivian to early Barremian, about 126-125 million years ago). Histriasaurus was a diplodocimorpha, a long-necked, whip-tailed giant that walked on four columnar legs. It had peg-like teeth and high vertebral spines. It may have had a sail on its back. Fossils of this sauropod were found in Croatia. The type species is H. boscarollii, named for Dario Boscarolli, who discovered the fossil site. Histriasaurus was named by Dalla Vecchia in 1998. It is probably closely related to, but more primitive than Rebbachisaurus.

Q: What dino. was discovered in 1988?
from Kelli W., Princeton, MN, USA; May 24, 2000

A: Lots of diniosaurs were found in 1988, including a relatively complete Herrerasaurus (Sereno). The year when a dinosaur is named is recorded and readily available in references. The year that a fossil was found (and even who actually discovered the fossil) is not always easy to find. Lots of dinosaurs were named in 1988 (the dinosaur fossils had been found earlier), including Aeolosaurus, Anserimimus, Cathetosaurus, Chassternbergia, Denversaurus, Giraffatitan, Hironosaurus, Kagasaurus, Kotasaurus, Nanotyrannus, Orodromeus, Protognathus, and Stenotholus.

A: The last of the dinosaurs went extinct 65 million years ago, during the K-T extinction.



Q: In response to an earlier Q&A, I disagree that the two new prosauropods are not possibly the earliest dinosaurs. Remember Bakker's Dinosaur Heresies? I think this dicovery is great for his theory on dinosaur evolution. These prosauropods probably had the twist-claws Bakker described. Being the first dinosaurs, they could have passed them down to primitive theropods, anchisaurs, and primitive ornithichians. Interestingly, Pisanosaurus has been interpreted as a possible heterodontosaur! The early heterodontosaurus branched off into the fabrosaurus, losing the claw, and the later, more familar heterodontosaurus that retained it in the later part of the Triassic. Also, aren't the prosauropods based on jaw fragments? Aren't we all assuming too much about these little creatures? Anyway, that's my position. I know this should be dino talk, but I want your reply. I also still don't know if we are talking about two individuals or two s! pecies.
from Brad, Woodville, ON, Canada; May 23, 2000

A: That's certainly an astute observation, but there's no way to know about the claws - plus, I don't think that the dating of the rock layers has been done by radioisotope analysis, and so is a bit hazy. Many paleontologists think that the saurischians branched off before the ornithischians (for example see The Evolution and Extinction of the Dinosaurs by Fastovsky and Weishample), although this may be because of Eoraptor. As to Pisanosaurus (the earliest ornithischian that is relatively well-known, dating from the late Triassic, roughly 220 million years ago), it is generally placed outside the heterodontosaurids, although it was once thought that it belonged to that group.

I think that it would be an amazing coincidence if the oldest dinosaur had already been found, especially when so little of the Earth's lands have even been searched for fossils.

Q: How did the Triassic dinosaurs die out.
from Mintaka A, state College, PA, USA; May 22, 2000

A: Most dinosaur groups (like most organisms) died out in background extinctions. These extinctions are not caused by major catastrophes or horrendous climactic changes, but by small changes in climate or habitat, depleted resources, competition, and other changes that require adaptation and flexibility.

At the end of the Triassic period there was a minor mass extinction that killed off many types of organisms, including many dinosaurs. The cause of this extinction is not known.

Q: What all can you tell me about the Jaxartosuarus dinosuar
from Curtis L., sanford, North Carolina, U.S.A; May 21, 2000

A: Very little is known about this dinosaur since only a part of the skull has been found (so far). Jaxartosaurus is pronounced jax-SAHR-toh-SAWR-us. Jaxartosaurus means "Jaxartes Lizard;" it was named for a river in Kazakhstan near where it was found. Jaxartosaurus was about 30 feet (9 m) long, and was a lambeosaurine hadrosaurid, a duck-billed dinosaur. Fragmentary fossils (just the skull roof and braincase) were found near the Jaxartes River in Kazakhstan. Only an incomplete skeleton was found. This wide-headed plant-eater had flat-topped teeth. It lived during the late Cretaceous period, about 91-83 million years ago. Jaxartosaurus was named by Riabinin in 1939. The type species is J. aralensis.

Q: What is the name of the dinosaur that stole and ate the other dinosaur eggs?
from deseriev, Azusa, Ca, US; May 19, 2000

A: Oviraptor (which means "egg thief") was given that name because it was found with eggs near it and it was assumed that it was stealing and eating those eggs. It was later found that those eggs were of the same species, so Oviraptor was found around its own eggs, and the name is probably inappropriate.



Q: the dinosaur lived mainly in the geologic time called the Mesozic period, which began 245 million years ago and ended 66 milion years ago. If you draw a timeline chart in which 1000 years equals one inch (so that the time of Christ and Julius Caesar is two inches away), the dinosaur will be approximately how far away A. 500 to 750 feet B. 1000 to 2000 feet C. 1 to 2 miles D 5 to 6 miles
from Karen, Houston, Texas, United States; May 19, 2000

A: Here's my chart of geologic time since the time of the dinosaurs. Your calculation should look something like this (the easiest way to do calculations like this is to work with the units, starting with what you know, and playing with the units to get where you want to be):

1 inch/1,000 years times 100,000 years times 1 ft/12 inches = roughly 8,000 feet. You can do the last conversion yourself (there are 5,280 ft in a mile).

Q: what is the size of the land area each dinosaur would need for survival?
from ?, spokane, washington, usa; May 14, 2000

A: That isn't known. First of all, it would differ from dinosaur to dinosaur; the huge sauropods (like Brachiosaurus) must have needed a huge area from which to find food, but small dinosaurs, like Compsognathus) may have had a small range. The size of a dinosaur's range would be a function of the amount of food it ate and how much food per area there was. Neither of these quantities is known (yet).

Q: Can someone please tell me what a Macrauchenia is if it isn't a dinosaur, thank you, Ewan.
from Ewan G, Shaftesbury, Dorset, England; May 13, 2000

A: Macrauchenia was an early hoofed mammal with a long neck; it may have had a long trunk. Macrauchenia was 10 feet ( 3 m) long and had three-toed, rhino-like feet. This quadruped was an herbivore (a plant-eater). Macrauchenia lived during the Pleistocene. Fossils have been found in Argentina, South America. Classification: Class Mammalia (mammals), Order Litopterna (horse-like and camel-like mammals), Family Macraucheniidae.

Q: Did lemurs and dinosaurs live at the same time? The reason I ask is in the new Disney movie "Dinosaur" there are lemurs living 65 mya and I think that's incorrect but I could be wrong.
from dinofriek, Algonquin, IL, USA; May 12, 2000

A: The earliest-known lemurs (family Lemuridae) date from about 50 million years ago, so they did not live with the dinosaurs. Other pre-primates (primatomorphs like Plesiadapis, a squirrel-like 2 1/2 ft long with teeth like those of rodents) were around during the late Paleocene, about 58 million years ago).

Q: I am doing a report on rhamphorhynchus. I cannot find the enemies or its protection. Could you help me please? Thanks!
from Nick, ?, Indiana, ?; May 11, 2000

A: None of the plesiosaurs were very well protected from enemies. Flying away would be the best defense. Rhamphorhynchus had a long, pointed beak with many teeth. There are no documented enemies (that is, there have been no fossils of Rhamphorhynchus found inside another animal's body cavity, in another animal's dung, or found in a fight to the death). For possible enemies, go to the page on late Jurassic period fossils, and look for meat-eaters that lived in Europe and Africa. For more information on Rhamphorhynchus, click here.



Q: Did all of the dinosaus every single on of them come from the Eoraptors?
from raul, toroonto, ontario, canada; May 11, 2000

A: No, not at all. Although Eoraptor was a very early dinosaur, the dinosaurs had already split into the saurischians and ornithischians by then.



Q: What does the inside structure of the Eoraptor look like?
from Sharon, toronto, ont., canada; May 11, 2000

A: No one knows, since only the fossilized bones of Eoraptor have been found.

Q: how did scientist determine if dinosaurs were smart?
from Sarah L, denver, colorado, usa; May 11, 2000

A: Although it's not a guaranteed method, paleontologists use the ratio of an animal's brain size to its body mass. This tells you the relative intelligence among the dinosaurs. For more information on this, click here.



Q: dose the Compsogathus hunt alone or in a group? answer asap please
from jon, ???, TX, USA; May 10, 2000

Q: do you have Information on Piatnitzkysaurus
from willie C., Joplin, Mo., United states; May 10, 2000

A: Piatnitzkysaurus (meaning "[A.] Piatnitzky lizard") was a theropod dinosaur that was 14 ft (4.3 m) long. This meat-eater had a large head, a short neck, small arms, a bulky body and clawed toes; it was similar to Allosaurus. Fossils have been found in Argentina. Piatnitzkysaurus was a theropod that lived during the late Triassic period, about 169-163 million years ago. The type species is P. floresi.



Q: how do raptor defend them selfs
from ryan p, florssant, mo, us; May 10, 2000

A: Raptors (dromaeosaurids like Velociraptor, Deinonychus, and Utahraptor) were well-armed. They had a large, deadly, sickle-shaped clae on one toe of each foot. Their other digits also had smaller claws and they had sharp teeth.



Q: I'd like to know some info on Ichthyosaurus, particularly what type of eater it was. Thanks
from ?, ?, ?, ?; May 10, 2000

A: Ichthyosaurus was a carnivore that ate mostly fish, plus some cephalopods. For more information on Ichthyosaurus, click here.



Q: WHICH DINOSAUR WAS THE FASTEST?
from ?, ?, ?, ?; May 10, 2000

A: The speediest dinosaurs were probably the bird-like bipedal carnivores (theropods) with long, slim hind-limbs and light bodies (hollow bones and a streamlined body), like Gallimimus and Ornithomimus. It's impossible to tell which one was actually the fastest. If all we had were bones of modern-day mammals, it would be impossible to tell that the cheetah is the fastest mammal.

Q: what is the kritosaurus and is there any information you can give me regarding it..
from jordan n, milwaukee, wi, usa; May 9, 2000

A: Kritosaurus (meaning "Noble lizard") is a doubtful genus; this fossils may actually be Gryposaurus, but may be a separate genus. It was a duck-billed dinosaur from the late Cretaceous period, about 76 to 65 million years ago. This hadrosaurid was a plant-eater that was about 30 feet (9 m) long. It had a flat head and a big bump on its snout. It is known from a fragmentary skull found in the San Juan basin of New Mexico, USA. Kritosaurus was named by fossil hunter Barnum Brown in 1910. The type species is K. navajovius.



Q: 1. How do Eoraptors have their young? Do they lay eggs or have them live? 2. How do they raise their young? Do they live in families, groups or leave them alone?
from Cassie S., Estacada, Oregon, USA; May 9, 2000

A: Neither Eoraptor eggs nor nests have been found yet, so no one knows.



Q: What were some of the eniemies of the triceratops? I need this information for a report I am doing in first grade. Thank you .
from Alyson Y, Alexandria, VA, USA; May 9, 2000

Q: Bakker made up a lot of terminology for Raptor Red. Here are the babies- Baby Astrodon- Calf Baby Utahraptor- Chick Bakker seems to use bull and calf for plant-eaters only. And I lost my copy of Raptor Red, do you know where I can get a new one? I also have some poems. I guess I shouldn't be too shy to share them ,since I got 100 out of 100 on my English assignment when I handed them in.
from Brad, Woodville, ON, Canada; May 9, 2000

A: I haven't seen calf or chick used elsewhere - have you? I've seen the terms bull and cow used for both plant- and meat-eaters in many sources (including the recent show "Walking with Dinosaurs").



Q: What is a Female, a male, and a child T-Rex called? ie. a bull, mare, calf?
from Joseph R, Highland, CA, USA; May 9, 2000

A: Bull and cow are sometimes used for the male female. A newly-hatched dinosaur is generally called a hatchling and as it grows, it is called a juvenile (I've never heard of dinosaur young called calves).



Q: What were the first dino's like?
from Rosie S., Alden, NY, U.S.A.; May 9, 2000

A: The earliest dinosuars were realtively small. Some of the early dinosaurs include prosauropods (small-headed, long-necked plant-eaters) found in Madagascar and theropods (meat-eaeters) found in Argentina.



Q: Why do the Brachiosuaruses have such long necks and how did they get them
from Trenton V, Traverse city, michigan, USA; May 9, 2000

A: That's just like asking why a giraffe has a long neck and how it got it. The long neck developed over millions of years, probably as an adaptation for getting leaves high in the trees. Natural selection would be the mechanism. For more information on Brachiosaurus, click here.

Q: how did the heterodontosaurus go extinct?
from ?, ?, ?, ?; May 8, 2000

A: Heterodontosaurus went extinct about 200 million years ago, during the early Jurassic period. This extinction may have bene related to the minor mass extinction toward the end of the early Jurassic period (about 190- 195 million years ago) in which more than 80% of marine bivalve species and many other shallow-water species died out. The cause of this extinction is unknown.



Q: how did dinosuars become extinct in the TRIASSIC PERIOD?
from db, martinez, ga, usa; May 8, 2000

A: The Triassic period ended with a mass extinction caused by huge volcanic eruptions about 208-213 million years ago. 35% of all animal families die out, including most labyrinthodont amphibians, conodonts, and all marine reptiles except ichthyosaurs.

from DeAndrea Z., Texas City, Texas, USA; May 7, 2000

A: Alamosaurus (meaning "Ojo Alamo [New Mexico] lizard" ) was a long-necked, whip-tailed dinosaur about 69 feet (21 m) long and weighed perhaps 30 tons (20000 kg). It was a quadrupedal, plant-eater from New Mexico, Texas, and Utah, USA during the late Cretaceous period, about 73 million to 65 million years ago. It was a sauropod and a Titanosaurid that may have had some body armor. It was named by Gilmore in 1922. The type species is A. sanjuanensis For a printout on Alamosaurus, click here.



Q: what geologic period did mammals and dinosaurs first appear?
from mike m., oregon, ohio, u.s.; May 7, 2000

A: The Triassic period.



Q: *Many scientists think that dinosaurs were warm blooded, which would have allowed then to maintain high activity levels over a broader range of environmental temperatures than cold-blooded animals. Explain how this adaption would have given dinosaurs an advantage over other organisms in their environments???
from Angela, alden, ny, us; May 7, 2000

A: If you're warm-blooded, you can be active day or night, in cold or warm weather. Most cold-blooded animals must warm themselves in the morning sun before they can be active; if you are warm-blooded, you can catch them easily while they are warming up. There are many more advantage (and disadvantage). For a page on this, click here.



Q: What do scientists think dinosaurs evolved from? What were the first dinosaurs like?
from Angela c, alden, ny, us; May 7, 2000

from Hi!, Beaverton, Oregon, U.S.A.; May 6, 2000

A: The dinosaur with the longest name is Micropachycephalosaurus.



Q: What adaptions would allow a land animal to compete in an aquatic environment?
from Angela c, a., ny, usa; May 6, 2000

A: It would need a way to get food in the water, a way (or ways) to avoid becoming another organism's food, and a way to survive in that environment (like adapt to the temperature, etc.).



Q: Where did dinosaurs come from? And How long did it take for all of the Eoraptor's to evolve into these gigantic dinosaurs.??? Please answer......This is the third time I'm asking this question. I really need to know cause its for a school project, that is due in 4 days. Please answer soon. Very desperate
from priya K, toronto, ont, Can; May 6, 2000

A: For a page on dinosaur evolution, click here. Jurassic sauropods probably didn't evolve from Eoraptor (which may have been a theropod, in which case it had already split off from the sauropod dinosaurs). The sauropods may have evolved from prosauropods, or from earlier, as yet unknown dinosaurs. For a cladogram of dinosaurs that shows the evolutionary relationships between the dinosaurs, click here.



Q: I have been searching for information about the duckbilled platypus for two weeks for a school project. I've searched everywhere to gather as much info as I possibly can.

from Elizabeth M., Bedford, Indiana, USA; May 6, 2000

A: The largest-known dinosaur eggs are about a foot in diameter. For more information on dinosaur eggs, click here.



Q: What insects were around to bug the dinosaurs? I'd just like to know roughly when these groups appeared, because i just bought a book about how to draw insects, and I want to mix them with my dinosaur drawings. - Ants - Black Flies - Bumblebees - Earwigs - Ladybugs - Leaf Insects - Praying Mantises I don't care if you find them all, anything would be appreciated.
from Brad, Woodville, ON, Canada; May 6, 2000

A: There were many insects during the Mesozoic Era. Unfortunately, insect fossils are very rare, so the scientific knowledge of insect evolution is incomplete. Centipedes and millipedes appeared during the Silurian (over 400 million years ago), springtails appeared during the Devonian (over 350 mya) and the first winged insects appeared over 300 million years ago. Beetles evolved during the Permian period, and huge dragonflies hunted during the Mesozoic. True flies appeared during the Triassic period. The earliest-known butterflies are from the Cretaceous period (about 130 million years ago) as are the earliest-known ants and crickets. Bees also appeared during the Cretaceous (paralleling the development of flowering plants). For more information, click here.

Q: Why are so many dinosaur bones found in South Dakota?
from esweet, rochester, ny, usa; May 5, 2000

A: The badlands of South Dakota, USA have vast expanses of exposed ancient rocks which make it relatively easy to find some of the fossils that are buried there.



Q: Please answer asap!!!! i am doing a report on the dinosaur Muttaburasaurus. Can you please tell me where i can find some information on it? Thanks alot
from brad d, somerdale, nj, usa; May 5, 2000

A: (pronounced mutt-ah-BUHR-ah-SAWR-us) Muttaburrasaurus (meaning "Muttaburra (Australia) lizard" ) was an ornithopod, a plant-eating dinosaur about 24 feet (7 m) long, dating from the middle Cretaceous period, about 113-97.5 million years ago. It had a large bulge on its long snout between its eyes and its mouth, a flattened thumb spike, hoof-like claws, and teeth that worked like shears. The bony bump on its snout may have been associated with its sense of smell or its ability to make sounds. Muttaburrasaurus is either an Iguanodontid or a Camptosaurid dinosaur. It was described and named by Ralph E. Molinar and Alan Bartholomai in 1981 from a fossil found in Queensland, Australia. The type species is M. langdoni.



Q: Why are dinosaur fossils found in the places they are found? Is that where the dinosaurs mostly lived, or is there something about those places that better preserves fossils? (are so many fossils found in the badlands in Alberta because more dinosaurs lived there than in other places, or because there is something in that place that makes better fossilizing conditions?)
from Jonathan B, Dundas, Ontario, Canada; May 4, 2000

A: Dinosaurs lived in many different environments on land during the Mesozoic Era, but some envionments made fossilization more likely. Fossils are more easily found in places like badlands because erosion has exposed old layers of rock and fossils, but there weren't necessarily more dinosaurs there to begin with. Dinosaur fossils aren't found in some areas where dinosaurs lived because the Mesozoic Era rock layers are well-buried, or fossils didn't form in that location because conditions were adverse to the fossilization process. Dinosaurs fossils aren't found in some areas because dinosaurs either didn't fossilize well there, or dinosaurs didn't live there (often because that location was under water during the Mesozoic Era, when sea levels were high).



Q: where I can find this type of dinasour,Piatnitzkysours.

Q: Why haven't these 232 m.y. old dinosaur from Madagascar you mention been given a proper scientific name? Weren't they reported in the news over six months ago?
from Brad, Woodville, ON, Canada; May 4, 2000

A: John Flynn et al. published early findings in Nature (Sept. 2, 1999 ) and Science (Oct. 22, 1999). They found not only the earliest-known dinosaurs, but the jaw bone of a new, early, shrew-sized species of mammal from 165 mya (which they named Ambondro mahabo), and other early life. I don't think that the name of the dinosaur has been published yet - I'm not sure they're entirely out of their matrix yet. I'll add it to the site as soon as its published.



Q: How do you KNOW what the climate was like in the Mesozoic Era? This is for a geology class.
from Heather P, Honolulu, Hawai'i, USA; May 4, 2000

A: There's geochemical evidence (like the way ancient soils formed, and did they form year-round, indicating a warm climate or was there a winter break, indicating a cold climate), biological evidence (like seeing organisms that could only live in certain climates), and physical evidence (like seeing the boulders and depressions caused by ancient glaciers, even though the glaciers have melted long ago).

The large head had huge jaws (up to 4.7 ft =1.45 m long) with many teeth. The jaws could open about 3 feet (1 m). The lower jaw is loosely hinged to the skull with a moveable joint on each side (behind the teeth). This loose joint let it swallow huge prey, like some snakes. They hunted fish, turtles, mollusks, and shellfish. It Mosasaurus lived in the North Atlantic Ocean. Mosasaurus maximus found in Onion Creek, Texas, USA. It was 30 foot (9 m) long and its tail was about 12 ft (3.7 m) long. This huge reptile was discovered in 1934 by University of Texas geology students Clyde Ikins. The first Mosasaur, Mosasaurus hoffmani, was found in the Netherlands in 1780. It was named in 1822 by W.D. Conybeare. Mosasaurs are related to modern-day monitor lizards.
