Quiz Answer Key and Fun Facts

1. This dinosaur is very popular among kids and adults. Its ancestor also did the dino paddle. What monster from many movies, books and shows had some very small arms but a very large head and massive teeth?

Answer: Tyrannosaurus Rex

Tyrannosaurus rex (T-rex) is one of the most famous of dinosaurs from the many creatures that developed during the 200 million years dinosaurs were around on earth. An ancestor of T-rex from 100 million years ago may have waded through water based on the claw marks in an old riverbed in China. T-rex may also have gone into the water to cool off, hunt prey, or to get to the other side of a river or lake.

2. What huge shark-like swimming creature from the age of the dinosaurs would have dwarfed a great white shark?

Answer: Megalodon

Megalodon lived about 28 to 1.5 million years ago and fossils of this huge shark-like creature have been found all over the world in the oceans and even in the deepest part of the Pacific Ocean. Many people used to think that its fossils of teeth were those from dragons. Its name means "big tooth". No one knows why it went extinct or even if it really did!

3. This smaller dinosaur (the swift plunderer) had very sharp claws as well as hook-like weapons on its back claws which it lashed out at with at its prey. What was its name?

Answer: Velociraptor

Velociraptors probably did not hunt in packs as shown in the "Jurassic Park" movies; they were also feathered. It looked a lot like a very big chicken except for sickle-like back toes. Wonder if it tasted like a chicken too?

4. What dinosaur had a very long tube that extended from the back of its head like a snorkel?

Answer: Parasaurolophus

The parasaurolophus had very heavy boned front legs which would have helped it with wading into rivers to get away from a T-rex-like dinosaur. Its snorkel-like tube on the back of its head had no hole and they probably spent most of their time on land when not using water for running away from meat-eating dinosaurs.

5. This is a flying reptile which had very light and delicate bones and was around for many of the millions of years that dinosaurs existed.

Answer: Pterosaur

Pterosaurs were flying reptiles. Many of the fossils of pterosaurs were found by what had been seashores or other places in water. These creatures would swoop down and pick up fish from the surface of the water.

6. Baryonyx was a dinosaur with a long crocodile-like snout and nearly foot-long claws. It may have hunted with these claws by river beds much like what modern animal?

Answer: Bear

Baryonyx's name means "heavy claw". It ate fish mostly as is proven by fossilized fish found in one of these dinosaurs' stomach. It probably waded into water and would scoop up fish with its hook like claws into its crocodile-like mouth.

7. Kronosaurus was a sea reptile which used what to move forward?

Answer: Flippers

Kronosaurus had a very thick head with a short neck and very big flippers which it probably flapped up-and-down like a penguin to move. It had a fairly small tail. It is named after a Greek god-- Kronos.

8. Triceratops lived about the same age as which other ferocious dinosaur?

Answer: Tyrannosaurus Rex

Triceratops probably ate palm fronds as its teeth were not made for crushing nuts, leaves, and fruits. It lived at the same time as T-rex and would battle this ferocious giant with its horns. Triceratops also battled with each other according to wounds found in triceratops fossils. These dinosaurs probably were not big swimmers as their heads were fairly close to the ground.

9. This fearsome dinosaur may have hunted in packs and had an almost foot-long claw on each of its back feet as well as smaller claws on its arms. What was the name of this dinosaur whose fossil was first discovered in the US in 1975 and was identified as a separate species in 1991?

Answer: Utahraptor

Utahraptor lived about 120 to 130 million years ago and probably hunted iguanodons. It was the biggest raptor. This dinosaur probably went rarely into the waters of the lands that would become North America.

10. What dinosaur was the size of a bus, had a brain the size of a walnut, may have had a second "brain" near its tail, and had 17 bony plates on its back?

Answer: Stegosaurus

Living from 156 to 140 million years ago, the stegosaurus had a number of different species under this name. Some had four almost three foot spikes on its tail for defense. Other stegosaurus species had eight three foot tail spikes. This dinosaur had hind feet which were much longer than its short front feet making its head stay quite close to the ground where it ate low lying ferns.

Its name means "covered lizard".
