Q: I am doing a report on saltopus. I have 2 questions. I need the family name that saltopus belonged to. Also was saltopus an insectivore or a carnivore. Your info sheet lists saltopus as a carnivore,but your question sheet regarding "who is the smallest dinosaur" lists saltopus as an insectivore. Which is correct?
from jenny w, buffalo, ny, us; October 23, 2000

A: Saltopus was either a very early theropod (of an unknown family) or it may have been a lagosuchid (primitive reptiles that led to the dinosaurs) or an ornithosuchian (not dinosaurs, but closely-related archosauromorphs). Saltopus is only known from fragmentary remains and its classification is uncertain.

Insectivores (insect-eaters) are a type of carnivore (carnivores are organisms that eat other organisms). Saltopus was too small to be able to kill animals much larger than Mesozoic Era insects, but like many modern-day insectivores, it may also have eaten dead animals that it found.

2. Astrodon, Pleurocoelus, and Priconodon have been found in Maryland. For more dinosaur finds listed by location, click here.



Q: Did You Make Up all The Dinosaurs Names?
from ?, ?, ?, ?; October 22, 2000

Sometimes the dinosaur is given a name that describes something unusual about it's body, head, or feet. Some are named after the location where they are found, their behavior, size, or in honor of a person. For more information on naming dinosaurs, click here.

Q: I heard that there was a dinosaur that a paleontologist put the wrong head on the skeleton. Can you tell me what the name of it was?
from Jason S, New York Mills, Minnesota, United States; October 19, 2000

A: Yes -it was Brontosaurus (now called Apatosaurus). The original Brontosaurus fossil, found in 1879, lacked a skull (as many fossils do). Othniel Marsh added a skull found miles away (this skull did not belong to the Brontosaurus, but to a Camarasaurus). In 1900, Henry Osborn assembled another skull-less Brontosaurus at the American Museum of Natural History in New York City, adding a cast of Marsh's skull. In 1915, Earl Douglass of the Carnegie Museum found a Brontosaurus fossil that included the skull, but because of Osborn's influence, the Carnegie displayed the fossil skull-less. When Douglas died in 1932, the incorrect skull was put on display! It wasn't until 1975 that the proper skull was mounted on Brontosaurus/Apatosaurus fossils in museums.



Q: How do you no which dinosur is which.
from Rachel P., Salado, Texas, ?; October 19, 2000

A: Dinosaurs bones often differ greatly in size and shape. It is pretty easy to tell the difference between some dinosaurs, like a giant one versus a small one, but sometimes it is very hars to know what dinosaur you've found.

For example, if you find a fossil whose bones are the same size and shape as those of T. rex, your fossil is probably a T. rex. Sometimes, however, it is difficult to determine which group (family, genus and species) a set of bones belongs to (or even if the set of bones belongs to a single type of dinosaur - sometimes many dinosaurs are jumbled together in a bonebed). If a new dinosaur is similar but not exactly the same as a known dinosaur, it is difficult to determine if the new dinosaur belongs to new group or if it belongs to the old group, but is perhaps different in age (maybe you found a young specimen of that dinosaur, which looks different than the adults) or gender (sometimes the males and females are quite different - sometimes they are similar in appearance).

Q: I have to do a math project on careers... Um. I choose paleontology as one of the careers I'm interested in. I have to say what the salary is.. and state a problem that a paleontologist would have to solve using math. Um.. Yeah. Thanks
from Lyssi B, ?, ?, USA; October 18, 2000

A: The salary range is huge, depending on what you do as a paleontologist. Some paleontologists work for universities, some work at museums, some work for oil (or other) companies, some work for the government, some collect fossils, and some write books. Some paleontologists do many of these activities.

An example of a math problem in paleontology is determining the approximate weight of a dinosaur. You first have to make a model of the dinosaur, then determine its volume (by immersing the model into water and seeing how much water it displaces). Then you have to multiply by the scale of the dinosaur to find the actual volume (for example, if the model was 1/100 of the original dinosaur's size, you have to multiply by 100). Then you have to determine the dinosaur's density (by using the density of modern-day animals that you think would be similar in structure) and then multiply the density by the volume to find the approximate weight.

from Caleb H.; Clifford S.; Paul M., Parkersburg, West Virginia, U.S.A.; October 18, 2000

Q: I have a project due tomarrow and was wondering if you could answer this question. Why can't you find dinosaur fossils in Ohio?
from Erin, ?, ?, ?; October 12, 2000

A: Dinosaurs probably lived in what is now Ohio, but no sedimentary rocks were deposited there during the Mesozoic Era, so there are no fossils. Instead of rock formation, there was rock erosion in Ohio during the Mesozoic (it was probably a relatively high area). This erosion would wash or crumble any dinosaur bones/fossils away. For more information, see "Fossils of Ohio," by Rodney M. Feldman, Ohio Geological Survey Bulletin 70, 1996.

A: The Precambrian:
EON ERA PERIOD EPOCH PIVOTAL EVENTS
Proterozoic Eon
2.5 billion years ago to
540 mya
- Vendian Period
600 to 540 Million Years Ago
Vendian biota (Ediacara fauna), multi-celled, animals appear, including sponges. A mass extinction occurred. The continents had merged into a single supercontinent called Rodinia.
- First multicellular life: colonial algae and soft-bodied invertebrates appear. Oxygen build-up in the Mid-Proterozoic.
Archeozoic Eon
(Archean)

3.9 to 2.5 billion years ago
- - "Ancient Life" - The first life forms evolve - one celled organisms. Blue-green algae, archaeans, and bacteria appear in the sea. This begins to free oxygen into the atmosphere.
Hadean Eon
4.6 to 3.9 billion years ago
- - "Rockless Eon" - The solidifying of the Earth's continental and oceanic crusts.

Q: Could you please tell me a little bit about the evolution of the pterodactyl. I'm doing a project on evolution, so I also need to know whether they use the carbon methods to date all dinosaur fossils. Any answers would be greatly appreciated. I need the inofrmation B4 October 9th 2000
from Sarah G, Stirling, Ontario, Canada; October 8, 2000

A: Carbon dating is not used on dinosaurs (or Pterodactly) fossils because it's half life is too short. The half-life of carbon-14 is 5,568 years. That means that half of the C-14 decays (into nitrogen-14) in 5,568 years. Half of the remaining C-14 decays in the next 5,568 years, etc. This is too short a half-life to date dinosaurs; C-14 dating is useful for dating items up to about 50,000 - 60,000 years ago (useful for dating organiams like Neanderthal man and ice age animals).

Uranium-235 (which has a half-life of over 700 million years) is used to date the lava layers surrounding dinosaur-era fossils. For more information on dating fossils, click here.

I don't know anything about the evoltion of Pterodactyls. For other information on Pterodactyls, click here.

A: Thank you! I don't know how they were hunted, but the hides, tusks and sinews (stringy, elastic tendons) were certainly used by people. The hides were used for clothing, bedding, etc. The tusks were probably used for a lot of things - a sturdy, pointed object often comes in handy. Some tusks were even carved as artwork. Sinews are strong, pliable strings, and can connect things, like a stick of wood and a stone, making a hammer. The bones may have also been used. For a mastodon printout, click here.
