Q: If "Walking With Dinosaurs" said that Liopleurodon was up to 80 feet long, and you guys say that it's up to 49 feet long, than who's right?
from Charles X., Louisville, Colorado, USA; November 20, 2000

A: The type species of Liopleurodon (L. ferox, Sauvage 1873 ) was estimated to be 12 - 15 meters (39-50 ft) long (L. ferox is the largest-known species of the genus Liopleurodon). Most Liopleurodon fossils are in that size range. For a good page on pesiosaurs, see the entry on Liopleurodon at: http://www.isgs.uiuc.edu/dinos/dml/names/ples.html. All of my reference books cite the smaller size (which we cite), since most known specimen are in that size range (for example, see the Simon and Schuster Encyclopedia of Dinosaurs and other Prehistoric Creatures, 1999, gives Liopleurodon's length as 39 ft = 12m). Note: since no complete fossils of Liopleurodon have been found, Liopleurodon's size is only an estimate (only isolated vertebrae backbones, jaw parts, and teeth are known). I can't find a single source (other than that TV show or those using that show as a primary reference) of a Liopleurodon 80 feet long (Leslie Noe was reportedly working on a really huge pliosaur, possibly Liopleurodon, in the late 1990's in England - perhaps this is what Walking with Dinosaurs was referencing). There's a long history of overestimating the size of prehistoric animals (especiallly pliosaurs) so our site tends to be conservative regarding size estimates. There's a famous Kronosaurus (another large plesiosaur) from Harvard University whose size was grossly overestimated for years (extra vertebrae were inadvertently added); only recently has its size been changed to be more in line with other known specimen of that genus (it went from 50 to 30 feet long). For another good page on pliosaur size (and examples of size overestimation), see: http://www.dinosauria.com/dispatches/19981108001.html



Q: what make's a dinosaur part of a group called sauropods. And what does it mean to be a sauropods
from ruthy A, aguadilla, ?, Puerto Rico; November 20, 2000

A: Sauropods were an an infraorder of quadrupedal, plant-eating saurischian dinosaurs. They had very long necks, small heads with blunt teeth, a small brain, and long tails for counterbalancing their necks. They had large guts, which were necessary for digesting huge amounts of plant material. They walked on four short, thick, five-toed legs. For more information on Sauropods, click here.



Q: When did dinosaurs roam the earth?
from Samara H, Detroit, Michigan, ?; November 20, 2000

from patricia p, penguin, tasmania, australia; November 19, 2000

A: When a scientist discovers a new type of dinosaur, that scientist gives the dinosaur a name. The name can't be right or wrong, it's just a name. For example, when a three-horned dinosaur was found, the scientist Othniel Marsh named it Triceratops (which means three-horned head). He could have given it another name, but the decision was essentially his. For more information on naming, dinosaurs, click here.



Q: How much did the brontosaurus weigh, and how long and tall was it?
from Jessica S, Arlington, WA, United Stated; November 19, 2000

A: For information on Brontosaurus (now called Apatosaurus), click here.



Q: Why doesn't coprolite smell???(TELL ME VERY, VERY, VERY SOON!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
from Mike Z., Edison, NJ, USA; November 19, 2000

A: The smell from feces is the decaying organic matter. In coprolites (fossilized feces), the organic materials have been replaced by rock-like minerals (which don't smell).



Q: HELP!!!!!!!!!!!!!How do scientists identify minerals in the substance?
from ?, ?, ?, USA; November 19, 2000

A: Minerals are identified by their color, their streak (the color they leave when rubbed against a hard substance), their hardness (using the Moh's scale), their density (called specific gravity), their crystalline structure, and their refractive index (if transparent, how they bend light).



Q: Did dino's use coprolite to mark their territorries?(Hurry and tell me ASAP!!)
from ?, edison, NJ, USA; November 19, 2000

A: No, coprolites are fossilized dung, but if the question were, "Did dinosaurs use dung to mark their territory?" the answers is: no one knows.



Q: Can you tell how old coprolite is?(Please tell me soon)!!
from ?,?, NJ, NY, USA; November 19, 2000

A: They vary in age. You can date these fossils by looking at index fossils in the same layer in which they were found or by radioisotope dating the surrounding lava layers.



Q: Can coprolite contain minerals like iridium?? I NEED THE ANSWER ASAP. IT'S FOR MY SCIENCE HOMEWORK!!!!!
from Mike Z, Edison, NJ, USA; November 19, 2000

A: Coprolites, like other fossils, contain rock-like minerals containing calcium, silicon, iron, etc. Iridium is a very rare element found near the center of the Earth, in some asteroids, and in some unusual sedimentary layers of the Earth (like the K-T layer, during which a large asteroid probably hit the Earth, scattering iriduim). Iridium would probably not be found in coprilites.



Q: What is the Stegosurus enimies
from Sean N, Kearny, N.J, U.S; November 19, 2000

A: It isn't known with any certainly, but possible predators of Stegosaurus include all the large meat-eaters from western North America during the late Jurassic Period, about 156-140 million yeas ago (where and when Stegoaurus lived). Some of these meat-eaters included Allosaurus, Ceratosaurus, Marshosaurus, Torvosaurus, and maybe even packs of smaller meat-eaters like Ornitholestes. For more information on Stegosaurus, click here.



Q: Does the coprolite contain the DNA of the dino's?
from chun,c, edison, NJ, USA; November 19, 2000

A: The coprilite of a meat-eater could conceiveably contain the DNA of its victim (For example, a T. rex coprolite was found containing fragments of Triceratops frill, which may in the future be used to obtain Triceratops DNA). Unfortunately, there is no way to reconstruct DNA from fossils yet.



Q: need to know why prey need predators
from chris l, london, ?, england; November 19, 2000

A: The standard answer is that without predators, prey species would over-reproduce and some would starve anyway.



Q: list animals with six to eight legs
from vanbana, el paso, ?, ?; November 19, 2000

A: All insects have six legs. Arachnids (like spiders, ticks, and scorpions) and octopi have eight legs.



Q: What's the difference between omnivore, carnivore, and herbivore coprolite?(PLEASE TELL ME SOON!!!!!!!!!!!!)
from Michael Z., Edison, New Jersey, USA; November 19, 2000

A: When you examing the contents of the coprolite, you will find different things. The dung of a carnivore (meat-eater) may contain bits of bone fragments, hair, etc. For example, a T. rex coprolite was found containing fragments of Triceratops frill. The dung of an herbivore (plant-eater) will contain undigested bits of plants. An omnivore's dung will contain both.



Q: how did the Herrerasaurus Reproduce?
from Jane L., Orlando, FL, USA; November 19, 2000

Q: 1.did dinasaurs legsspralw out on the side or extend strait down under the body?
from Brandon B., Lutz, Flordia, U.S.A; November 19, 2000

A:

Dinosaur legs: upright position

Other reptiles: Sprawling legs
Dinosaur legs did not sprawl, they were relatively columnar.



Q: What was the "king" or leader of the dinosaurs? In other words, who lead and ruled the dinosaurs?
from zachary c, jericho, ny, united states; November 19, 2000

A: The dinosaurs were reptiles and did not have an advanced social structure with a leader or king. An individual herd or pack of dinosaurs may have had a big, physically dominating individual.



Q: Does the color change when coprolite is fossilized?
from Karthikeyan I, Edison, NJ, USA; November 19, 2000

A: Yes. Since most of the molecules in the dung are replaced by rock-like minerals, the color changes.



Q: Emergency!!!!!!!!!!!!! Why is dino poop called coprolite
from Karthikeyan I, Edison, NJ, USA; November 19, 2000

A: Dinosaur poop is not called coprolites; only fosilized dinosaur poop is called coprolites. Copro means "dung" (from the Greek word kopros). The ending "-lite" is a common ending for fossil or mineral terms, coming from the Greek word lithos, which means stone. The term coprolite was coined around 1830-1830.



Q: wwwwuzzzzaaaaappp! Does coprolite shrink during the petrification process?(Tell me soon)
from Karthikeyan I, Edison, NJ, USA; November 19, 2000

A: Yes, because they dry out.



Q: I need two answers asap.(there due monday) 1.Can coprolite be used as fossil fuel? 2.what kept coprolite from decay?
from Sarah T., Edison, NJ, USA; November 19, 2000

A: 1. No, coprolites cannot be used as fossil fuel. Coprolites are fossilized dung. Although dung burns, when it fossilizes, most of its original molecules are replaced by rock-like mineral.
2. The same factors that kept any fossilized thing from decaying, including being immediately buried in dry sand, earth, mud, anaerobic water, etc.

A: Click here for a page on Wegener and Pangaea.



Q: What kind of scientists study "Coprolite"?
from Karthikeyan I, Edison, NJ, USA; November 19, 2000

A: They're called ichnologists (they also study other trace fossils like footprints, tailprints, and nests), and they study fossilized dung to learn about the diet of the animal it came from.



Q: My family would like to take a trip to Chesapeake Bay to look for prehistoric shark teeth (especially Megladon) as we have heard that it is a particularly rich area for this. Can you let me know which are the best areas there that are open to the public for this?
from Harris S, Lake Ronkonkoma, New York, USA; November 18, 2000

A: I don't know.



Q: What is a Euthecadon (Tell me soon!)
from chun, Edison, NJ, USA; November 18, 2000

Q: could hadrosaurs such as parasauroluphus have knocked large predatory dinosaurs over with their tails? I have found many different opinions on this. I know they probably would have knocked themselves over two-footed, but what about four-footed? Also, would any dinosaurs form inter-species herds?
from russell p., seattle, wa, usa; November 18, 2000

A: I don't know. It sounds like a good topic of discussion for a dinosaur talk forum, you might want to post at the dinotalk section and see what responses you get.



Q: The canaliculi was the same in ornithischian dinos than in mammals?
from Maximiliano E., Bolivar, Buenos Aires, Argentina; November 18, 2000

A: Canaliculi (tiny passages in bone which connect blood vessels to cells) are similar for birds and ornithomimid dinosaurs, but are different in mammals and plant-eating dinosaurs (like Triceratops and duck-billed dinosaurs); in these, they were quite different (the canaliculi were jumbled in birds and dinosaurs, but were radially arranged in mammals).

from Mary J., New Brunswick, NJ, USA; November 18, 2000

A: They're called ichnologists (they also study other trace fossils like footprints, tailprints, and nests), and they study fossilized dung to learn about the diet of the animal it came from.



Q: What was the fossil type of the Iguanodon and where did it live?
from Whitney R, Arlington, Washinton, U.S.; November 18, 2000

A: Iguanodon was an ornithischian (bird-hipped) dinosaur. Its fossils have been found in Belgium, England, Germany, North Africa, and the USA. For more information on Iguanodon, click here.



Q: I read one of your Q and As and I was disapointed in the answer you gave. Q: Why did the big dinosaurs have such small brains? A: Good question. The large dinosaurs were essentially giant lawn mowers. They didn't have to do much in life but eat all day and occasionally reproduce. They were so large that predators weren't much of a problem, so a large brain wasn't necessary for survival. They lived for millions of years and probably died out when food sources (available plants) were depleted. A larger brain wouldn't have helped much in this respect. Predators that have to hunt to eat need large brains in order to find and then catch prey. Large plant-eaters don't need that much brain power, they just graze on plants. Small plant-eaters need more brains in order to avoid predators. The true reason they had small brains was because they were herbavors. They received no protein, and needing larger more complex stomachs. Preadators had larger brains was because meat was easier to digest therefore not needing such large stomachs, and gained protein from the meat, therefore the protein helped grow larger brains. Plus with out the larger stomachs they became sleaker and more agile. Meat makes you smart.
from Rob S., Virgina Beach, VA, USA; November 17, 2000

A: That questions and answer did not appear in ZoomDinosaurs - you must have seen it on another site - but I do agree with its original answer.

Q: wich dinosaur has the biggest claw
from ?, ?, ?, ?; November 5, 2000

A: Deinocheirus (meaning "terrible hand") had the biggest claw. It was a bipedal carnivore (meat-eater) from the late Cretaceous period. It is classified as a saurischian (lizard-hipped dinosaurs), a theropod, a coelurosaur, and an ornithomimid (bird mimic). Only the arms, hands, and claws of Deinocheirus have been found (in the Gobi desert of Mongolia in 1965). The arms are 8 feet (2.4 m) long and have three fingers with long, hook-like claws, 8-12 inches (20-30 cm) long. The hands alone were 2 feet (60 cm) long. Deinocheirus was probably one of the most deadly dinosaurs of the late Cretaceous period. It may have been larger that T. rex.

from KELLY G., CHATSWORTH, CALI, USA, DUH!; November 4, 2000

A: It if's true that most of the dinosaurs were cold-blooded, then they were mostly diurnal (most active during the day). This would make it easier for the mammals to be nocturnal (most active at night), when dinosaurs wouldn't be chasing them and eating them. Also, many of the early mammals seem to have had large eyes, and most mammals with large eyes are nocturnal.

A lot of things are found there (including many fossils), but the most unusual thing found there is a superabundance of the element iridium (which is rare on the Earth's crust) and shocked quartz (which can results from a meteor impact). Iridium is abundant on meteors (and toward the center of the Earth).



Q: Hi. I'm doing this really hard and big report on dinosaurs. I would really appreciate it if you'd please help me with a few questions. What modern animals resemble dinosaurs? What are two disadvantages of being endothermic in desert conditions? What are two advantages of being ectothermic in desert conditions? What is the function of the oesophagus and how did it work? Thank you so much for your help.
from ?, ?, ?, ?; November 3, 2000

A: Birds are the closest living relatives to dinosaurs (and the most similar). Being endothermic (generating their own body heat, or hot-blooded, like mammals and birds) has disadvantages include the need to eat a tremendous amount of food in order to maintain a relatively constant body temperature, and there is a lower-bound to size (the smallest have extremely high metabolic rates). Advantages of ectothermy (not generating their own body heat, or hot-blooded, like amphibians and lizards) include have to spend a lot less time finding and eating food, and they can wait out times of bad weather (extreme hot or cold). The esophagus is the tube to the stomach (some work using peristalsis).

Q: How might a climate change have affected the dinosaurs? Please hurry thankyou!
from dwight p, northhollywood, california, USA; November 4, 2000

A: When the climate changes, the plants in an area change (plants that cannot live in the new climate die, and new plants take over). Animals that ate the old plants cannot necessarily eat the new plants, and they have to either move or die. The predators who ate that type of animal are then affected, and either have to find new prey, move, or die.

Q: who were t-rex and stegosaurus' enemies?
from melissa.k, tamworth, nsw, australia; November 3, 2000

A: T. rex was at the top of the food web - it had no predators. Stegosaurus' predators can only be guessed; for large meat-eaters that lived when it lived (during the late Jurassic period, 156-140 million years ago) and where it lived (western North America, Madagascar, South Africa, Isle of Wight, Southern India, and Mongolia), see this page and look for large meat-eaters that lived in the right places and right times.

Q: how are jawless fish and cartilaginous fish different?
from sherriC, pelham, alabama, montgomery; November 2, 2000

A: Jawless fish (Agnatha like lampreys and hagfish) do not have a hinged jaw, paired fins, or a bony skeleton (their skeleton is made from cartilage) ; they were the earliest vertebrates to evolve (and the first fish). Cartilaginous fish (Elasmobranchs like sharks, skates, and rays) also do not have a bony skeleton (their skeleton is also made from cartilage), but do have a hinged jaw and paired fins (making them more stable).

Q: is there a relationship between marsupials and dinosaurs or birds and dinosaurs? my third grade class is trying to determine if there is a relationship.
from pauline k, del rio, tx, usa; November 2, 2000

A: Birds probably evolved from the dinosaurs.

Dinosaurs and mammals evolved around the same time (during the Triassic period, roughly 220-230 million years ago), but the earliest mammals were not marsupials (marsupials evolved during the Cretaceous period, toward the end of the time of the dinosaurs). Mammals were not that prevalent during the time of the dinosaurs; when the dinosaurs went extinct (about 65 million years ago), the mammals (including the marsupials) became more diversified and more abundant.

Q: Which dinosaurs did not have scales?
from Kate M., Auckland, ?, New Zealand; November 1, 2000

A: Fossilized skin impressions have only been found for a small fraction of the known dinosaurs. Not much is known about dinosaur skin and there are plenty of debates among paleontologists about this topic. Most show bumpy skin, not scaly skin; only the huge plant-eaters seem to have had scaly skin. T. rex had bumpy skin, and ankylosaurs had leathery skin. For a page on dinosaur skin, click here. Also see an interesting page on dinosaur skin from dinosauria.
