An unnamed hadrosaur (duck-billed dinosaur) was found in Oregon. Click here for dinosaurs found in each state.
A: Click here.
A: Click here.
A: They went extinct at the end of the Cretaceous period during the K-T extinction.
A: Hadrosaurus belonged to the order Ornithischia.
For information on Pterodactyls (flying reptiles that lived during the time of the dinosaurs), click here.
A: There's the Cenozoic (65 million years ago until now), the Mesozoic (248-65 mya), and the Paleozoic (540 to 248 mya) (before this, the eras are not named). For a chart of geologic time, click here.
A: None, the kangaroo is a mammal and mammals did not evolve from the dinosaurs. Mammals evolved from pelycosaurs, mammal-like reptiles that lived before the time of the dinosaurs. Mammals evoled around the same time the dinosaurs evolved, during the Triassic period.
A: The dinosaurs lived from about 135 million years ago until about 65 million years ago, during the Mesozoic Era.

No one knows exactly howmany dinosaurs there were (either the number of species or the number of individuals). There are about 1,000 known genera, and many mnore species.
A: T. rex's favorite meal isn't known, but it is known that it did eat Triceratops (some ground-up frill bone was found in T. rex dung).
No dinosaurs have been found in Nevada. Click here for dinosaurs found in each state.
Utahraptor was about 20 feet long (6.5 m) and may have weighed about 1 ton.
There are monotremes, marsupials, and placental mammals. For more information on mammals, click here.
Like most dinosaurs, Deinonychus did not die out in a mass extinction. This common type of extinction is called a background extinction.
Brontosaurus (now called Apatosaurus) was huge - that was its primary defense. It also had a whip-like tail that may have been used for defense and some foot claws.
In order to determine whether or not a fossilized animal nurtured its young, fossil evidence of this must be found. On good type of evidence is finding fossilized eggs in nests with adults and hatchling nearby. This has not been found for Allosaurus, so it is not known whether or not it cared for its young.
A: Stegosaurus belonged to the order Ornithischia (the so-called bird-hipped dinosaurs). For more information on Stegosaurus, click here.
The birds evolved from the dinosaurs.
A: Click here.
A: No dinosaurs have been found in Virginia. Click here for dinosaurs found in each state.
A: Styracosaurus may have weighed roughly 3 ton.
A: Neither nests nor eggs from Corythosaurus have been found.
Hypacrosaurus is another duck-billed dinosaur that is very much like Corythosaurus (it may even be the same genus as Corythosaurus). A nest that may have belonged to Hypacrosaurus was found in Devil's Coulee, near Alberta, Canada. The nest had eight large, round eggs plus the bones of duck-bill embryos, probably those of Hypacrosaurus. The cantaloupe-sized eggs were laid in rows and were probably covered with sand and plant material.
A: The woolly mammoth's genus and species are Mammuthus primigenius. For more information on the woolly mammoth, click here.
A: Click here and scroll down to the section called "Classification."
A: I've never heard of any fossilized tongues being found. Since dinosaurs ranged in size from the size of a cicken to bigger than a house, their tongues must have ranged in size considerably also.
A: Click here for information on the Cretaceous period.
A: Supersaurus belonged to the order Saurischia (bird-hipped dinosaurs).
Sinosauropteryx and Caudipteryx
No one knows; no fossilized T. rex heart has been found.
A: For information on Deinonychus, click here.
A: Protoceratops was a ceratopsian (plant-eating dinosaurs with horns/frills) and an ornithischian (so-called bird-hipped dinosaurs).
A: The dinosaurs lived from about 230 million years ago until 65 million years ago (they lived about 165 million years).
A: For information on Centrosaurus, click here.
A: Ultrasauros was heavier but Supersaurus was longer.
A: No dinosaurs have been found in Wisconsin.
A: Tyrannosaurus rex lived during the late Cretaaceous period.
A: The pubis in Triceratops points backwards, parallel with the ischium.
A: Diplodocus was a huge dinosaur with a long neck and a whip-like tail. For more information on Diplodocus, click here.
T. rex went extinct 65 million years ago in the K-T mass extinction.
Edmontosaurus means "Edmonton [rock formation] llizard" because it was found in that rock formation in Canada. For more information on Edmontosaurus, click here.
A: T. rex lived during the late Cretaceous period, from about until 85 - 65 million years ago.
Click here for a chart of geologic time that lists when many of the animals evolved.
None. The rhinoceros is a mammal and mammals did not evolve from the dinosaurs (the birds are the living descendants of the dinosaurs). Mammals (including the rhino) evolved from pelycosaurs, mammal-like reptiles that lived before the dinosaurs evolved (mammals evolved during the Triassic period, about the same time as the dinosaurs evolved).
A: Protoceratops lived during the late Cretaceous period, about 86 to 71 million years ago.
No one knows. For information on Parasaurolophus, click here.
A: Click here for a page on the earliest dinosaur discoveries.
A: Eoraptor and two as yet un-named prosauropods from Madagascar are the oldest so far.
A: Pachycephalosaurus was a plant-eater.
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.
No, the dinosaurs ranged in size from chicken-sized to bigger than a house.
Yes. Scelidosaurus means "limb lizard."
Iguanodon was a plant-eater. It probably ate cycads, ferns, and other prehistoric plants with its tough, toothed beak. How much it ate is unknown because it's type of metabolism is unknown (if it maintained a constant internal temperature, like we do, then it would have to eat substantially more than if its temperature depended on the outside temperature). For other plant-eating dinosaurs that may have competed with Iguanodon for food, click here and look for other plant-eaters that lived in the same time (the early Cretaceous period, about 135-125 million years ago) and same place (Europe, North Africa, and North America).
A: No one knows. For more on this topic, see the faq's above.
Most of the remaining terrestrial dinosaurs went extinct 65 million years ago, just as the Mesozoic Era ended and the Cenozoic Era began. One duck-bill fossil has been found that dates from the very early Cenozoic (from roughly 64-58 million years ago).
Oviraptor was one of the omnivorous dinosaurs.
A: About 65 million years.
A hadrosaur (a duck-billled, plant-eating dinosaur) has been found in Minnesota. Click here for dinosaurs found in each state.
A: A Maiasaura bone fragment and a piece of eggshell from Maiasaura flew with astronaut Loren
Acton on an 8-day mission (Spacelab 2) in 1985. This was the first dinosaur in space. The historic Maiasaura fossils now reside at the Museum of the Rockies in Bozeman, Montana, USA.
A: The Troodontids (like Troodon) had the largest brain to body mass ratio.
The blue whale is more massive than any dinosaur.
Lambeosaurus and Janenschia (there are many more).
Megalosaurus was the first dinosaur to be named. For more information on the first named dinosaurs, click here.
Dinosaur legs: upright position
Other reptiles: Sprawling legs
A: They extended straight downwards.
A: The oldest dinosaurs are prosauropods from Madagascar - they date from about 230 million years ago.
A: Indiana doesn't have a state dinosaur (no dinosaur fossils have been found in Indiana). For Indiana state symbols, click here.
Pterodactlys were carnivores (meat-eaters). THe various Pterodactyloids ate fish (which they caught at the surface of the oceans), mollusks, crabs, perhaps plankton (for some species), insects, and scavenged dead animals on land.
A: The first Tyrannosaurus rex fossil was discovered by the famous fossil hunter Barnum Brown in 1902. Click here for more information.
A: No bone beds of Megalosaurus have been found, so it isn't known if lived or hunted in packs.
Rhamphorhynchus lived during the Mesozoic Era.
