Dinosaur

Dinosaurs (Greek: δεινόσαυρος, deinosauros) were the dominant vertebrate animals of terrestrial ecosystems for over 160 million years, from the late Triassic Period (about 230 million years ago) until the end of the Cretaceous period (65 million years ago), when most of them became extinct in theCretaceous-Tertiary extinction event. The living species of birds today may be classified as dinosaurs.

Since the first dinosaur fossils were recognized in the early nineteenth century, mounted dinosaur skeletons have become major attractions at museums around the world. Dinosaurs have become a part of world culture and remain consistently popular. They have been featured in best-selling books and films (notably Jurassic Park and the land that time forgot), and new discoveries are regularly covered by the media.

Dinosaurs have been featured in rise of the guardians as dreams created by the sandman.

Some dinosaurs were giant reptilian animals with horns,long necks,and spiked or clubbed tails. Some dinosaurs had more in common with birds than reptiles and had feathers on their bodies, ever a giant T-rex would start its life with tiny fluffy feathers. Dinosaurs were not totally cold blooded or warm blooded but were a little bit of something in between. Dinosaurs and crocodiles had a common ancestor and evolved from the same link of reptiles. Dinosaur were able to see their world in a huge why and could see some colors better than humans and some had the ability to see ultra violate light like cats,dogs,birds,and lizards.

When the two sisters of arendelle learned that dinosaurs weren't as extinct as everyone thought they met a young raptor who they first saw as a menacing danger but then got to know as a friend. The people of arendelle were a bit of a bunch of dinoaphobs for a while but slowly warmed up to them. The first time a dinosaur came out of the underground world was during 3,000 BC in the jungles of africa and the first sighting became a legend in swahili culture. The dinosaur was a sauropod named Mokele-mbembe.
