A: The dinosaurs lived on the supercontinent of Pangaea, which was breaking up during the Mesozoic Era.

A: The dinosaurs with the largest brain to body mass (probably indicating smarter dinosaurs) were the troodontids (like Troodon).

A: Triceratops was a plant-eater - it probably ate relatively low-lying plants like ferns and cycads.

A: Allosaurus was a top predator and didn't have any large enemies.

A: Click here.

A: I didn't see Giganotosaurus in Jurassic Park, but the problem you're alluding to is the fact that many of the dinosaurs in the movie were not from the Jurassic period, but from the Cretaceous period (Triceratops and T. rex were from the very late Cretaceous period).

A: Every organism has relatives.

A: For a roadrunner picture to color, click here.

A: The largest sauropods were probably 130 feet long.

A: Stegosaurus' most obvious adaptations were its triangular plates and its tail spikes.

A: T. rex is known to have eaten Triceratops (crushed Triceratops frill has been found in fossilized T. rex dung), and it probably ate other large animals, most of which (but not necessarily all) were probably dinosaurs.

A: Deinonychus weighed about 175 pounds (80 kg).

A: Sounds like Pteranodon, which is a pterosaur (not a dinosaur).

A: Click here for information on Pterodactyls.

A: Click here.

A: Fossilized T. rex dung has been found - it contained crushed Triceratops frill, so large plant-eating dinosaurs were certainly included in T. rex's diet.

A: See the faq's above.

A: Just relying on fossils material is it almost impossible. For some dinosaur species, two types of adult fossils have been found, differing in skeletal size, crest size, etc. These different types either represent females and males or are different sub-species (it is not certain).

A: The supercontinent Pangaea began separating during the late Triassic period. This, however, was not the first time that the Earth's continent's had formed a supercontinent and then drifted apart.

A: No one knows why.

A: ANSWER

A: Brontosaurus is now called Apatosaurus. For information on Apatosaurus/Brontosaurus, click here.

A: "Eric" is a 85 percent complete opalized leptocleidine pliosaur (a marine reptile) from the early Cretaceous in Australia (it was named to honor Eric Idle of Monty Python, the television comedy show). Eric the pliosaur was a marine carnivore (meat-eater) that was about 6.5 ft (2 m) long. Fish back bones (and gastroliths) were found in the stomach area of this fossil, so it likely ate small fish, catching them in its crocodile-like jaws..

A: Brontosaurus (now Apatosaurus) was originally displayed with the wrong skull. For more information on this early paleontological gaffe, see the entry on Apatosaurus.

A: See the FAQ above.

A: For information on Pterodactyls, click here.

A: An herbivore is an animal that eats plants. A carnivore is an animal that eats other animals (it is a meat eater). There have many similarities - they are both alive and need to eat to survive.

A: For a page on Cretaceous period plants, click here.

A: Click here for a page on Protoceratops.

A: A lot of dinosaurs had horns and ate plants, including Triceratops, Styracosaurus, Pentaceratops, and many other ceratopsians.

A: Zizhongosaurus weighed roughly 4400 kg.

A: Yes, the fossilized skin of some theropods (meat-eaters) has been found rto have feathers or protofeathers). For some information, click here.

A: Veliciraptor means "speedy thief." For more information on Velociraptor, click here.

A: Click here.

A: Primitive types of pterosaurs (rhamphorhynchoids) appeared during the Triassic, and died out at the end of the Jurassic period (during a minor extinction that occurred then). More advanced pterosaurs (pterodactyloids) appeared late in the Jurassic period and died out during the Cretaceous period, about 65 million years ago, during the K-T extinction.

Rhamphorhynchoids had long tails, short necks, and long, narrow wings; these were the first flying vertebrates and probably flapped their wings to fly. Pterodactyloids had shorter tails; most probably flapped their wings to fly, except the larger species.

A: The remaining late Cretaceous dinosaurs mostly went extinct about 65 million years ago.

A: The sauropods were a large group of plant-eating dinosaurs. For a page on sauropdods, click here.

A: Ankylosaurus lived during the late Cretaceous period, about 70-65 million years ago.

A: Spinosaurus had long, sharp teeth, powerful jaws, and clawed limbs.

A: Many, many animals use camouflage. For a page on some of them, click here.

A: Dinosaurs are commonly known by their scientific name (generally their genus). Triceratops' genus is Triceratops; there are many species, including T. horridus.

A: For information on Dilophosaurus, click here.

A: During the Jurassic, the supercontinent Pangaea was breaking up, forming a northern continent (called Laurasia) and southern continent (called Gondwanaland or Gondwana) separated by a shallow sea (called the Tethys Sea).

A: Click here.

A: The fastest dinosaurs were the long legged (especially long calved), light-weight, hollow-boned, ostrich-like dinosaurs like the ornithomimicd (which included Ornithomimus, Gallimimus, and Dromiceiomimus).

A: I don't think that anyone knows this. The movie Jurassic Park was great fun but was not very accurate in its dinosaur facts.

A: I sure hope not. I'm sure that they have been checked and double checked since the Archaeoraptor fiasco.

A: I don't know. The habitat that a dinosaur lived in is usually hard to surmise. Unless a lot of other organisms are found nearby, you can only guess (and even then, it isn't certain).

A: Zapsalis, Zephyrosaurus, Zigongosaurus, Zizhongosaurus, and Zuniceratops.

A: T. rex fossils have been found in western North America and in Mongolia. For more information , clicik here.

A: The Quaternary Period is the period of geologic time from 1.8 million years ago until now. The weather was has varied from ice ages to our current climate.
