A: Your dad is right. The largest dinosaur footprints are about the size of a bathtub; these are probably from large sauropods.

Q: What kind of teeth did the dinosaurs have?
from Charlie, Kearny, NJ, USA; March 26, 1999

A: Different dinosaurs had different teeth. Most meat-eaters had sharp teeth designed for tearing flesh. Most plant-eaters had blunter teeth that worked like lawn mowers. For more information on dinosaur teeth, click here.

from Lily P., Austin, TX, USA; March 18, 1999

A: Probably not. Jurassic Park was great movie but it took a lot of liberties with the facts. Velociraptor could probably dig faster than us, T. rex could probably run faster than us, etc. Also, it made Velociraptor much bigger than it actually was, and Dilophosaurus probably didn't spit poison. There were many other factual liberties taken in the movie.

Q: When was the last mass extinction period?
from stacy m., milwaukee, WI, USA; March 18, 1999

A: The last mass extinction was the Cretaceous-Tertiary (K-T) extinction, which happened 65 million years ago.

Q: How did the Plateosaurus defend itself and what animals did it attack or what animals might have attacked it?
from Nickolaus P., Mobile, AL, USA; March 18, 1999

A: Plateosaurus had short claws on its front and rear limbs, and weak, leaf-shaped teeth. These paltry defenses were probably not very effective against large predators, which had bigger claws, sharper teeth, and were stronger overall. Its best defense was to run away.

Plateosaurus lived during the late Triassic period in what is now Europe. For more information on Plateosaurus, click here.

Q: What does the Mesosaurus brazilenis have to do with continental drift???????????????????????
from LaTisha S, Cambridge, Ohio, USA; March 14, 1999

A: Fossils of Mesosaurus (one of the first marine reptiles, even older than the dinosaurs) were found in both South America and South Africa. These finds, plus the study of sedimentation and the fossil plant Glossopteris in these southern continents led Alexander duToit, a South African scientist, to bolster the idea of the past existence of a supercontinent in the southern hemisphere, Eduard Suess's Gondwanaland. This lent further support to A. Wegener's Continental Drift Theory.

Other fossils, like the animals Cynognathus and Lystrosaurus, also bolstered the theory.

Q: Were there any flying dinosaurs?
from Patrick H., Abilene, TX, USA; March 14, 1999

A: No, but there were other flying retptiles, the Pterosaurs, like Pteranodon, many Pterodactyloids, Rhamphorhynchus, and Quetzalcoatlus.

Q: How many dinosaurs have been discovered?
from Colton, Moscow, ID, USA; March 12, 1999

Q: what is the newest dinosaur fosil found?
from ??; March 9, 1999

A: There are new dinosaur fossils found all the time. For recent discoveries see the section on "Dinosaur News."

Q: Which is the most dangerous dinosaur.
from Kristina M., Stockholm, Sweden; March 9, 1999

A: The large raptors and other large, advanced theropods were probably the most dangerous because they were fast, smart, had HUGE claws, many sharp teeth, and ate meat. Dinosaurs like Megaraptor, Utahraptor, T. rex, Giganotosaurus, Carcharadontosaurus and Velociraptor were among the most dangerous dinosaurs yet discovered.

Q: Is it true that there are two kind of Dinosaurs.One a bird hip one and I forget the other one
from Mckinley B, Narragansett, Rhode Island, USA; March 9, 1999

A: The other is lizard-hipped (saurischian). For more information on these categories, click here.

Q: In your index of dinosaurs, you have highlighted some that are not dinosaurs. If they're not dinosaurs, why are they on the list and what is it that distinguishes from dinosaurs? For example, if Stegoceras is not a dinosaur, what is it?
from Joanne D., Easton, MA, USA; March 8, 1999

A: The non-dinosaurs are on the list because so many people have written and asked for information about those animals (and they usually ask for information about that "dinosaur ," not realizing that it isn't actually a dinosaur).

Some, like the pterosaurs are closely related to dinosaurs; the main distinguishing feature is the leg stance (dinosaurs legs are upright, pterosaur legs are sprawling, like most other reptiles). Others, like the Dimetrodon, are frequently confused with dinosaurs, but they are not even closely related. By the way, Stegoceras is a dinosaur.

I lost 2 dinosaur questions this morning, March 8, 1999. If you wrote then, please write again!

Q: Can you tell me where I can find more information
from m.b., Dupage, IL, USA; March 7, 1999

A: On what topic?

Q: Do dinosaurs have a sense of smell or taste?
from cody t., USA; March 7, 1999

A: There is no direct physical evidence in the fossils record about either the dinosaurs' sense of smell or taste. Dinosaurs that hunted may have used a sense of smell to help in the hunt (as many modern-day predators do), or they may have relied upon their sense of sight. The sense of taste was probably used to avoid poisoning which was probably useful for both herbivores and carnivores.

Q: How many teeth did Saltopus have?
from ??; March 7, 1999

A: This tiny meat-eater had dozens of sharp teeth (I can't find any references to the exact number, but it did have a lot). For more information on Saltopus, click here.

Q: Were there any dinosaurs that were classified as omnivores? I know that there were carnivores nad herbivores, but I am not sure of any that ate both meat and plants.
from Christopher S., San Antonio, Texas, USA; March 5, 1999

A: Yes, there were onminorous dinosaurs, like Ornithomimus. For more information in dinosaur diets, click here.

Q: How much did the Rhamphorhynchus weigh?
from M.B., Ohio, USA; March 2, 1999
