n. An animal believed to have lived in the ice age. It is unknown whether this animal is still alive today. It is a species of penguin. It looks like your average emperor penguin, but it has spots the resemble very closely to a giraffes skin. It also carries other characteristics of a giraffe, such as a five foot neck and 12 inch tongue.

This animal is commonly mistaken for some type dinosaur. It is in no way a reptile or related to any type of dinosaur.
Dinosaurous was once the ruler of its penguin species, but now nobody knows whats happened to it. My theory is that it separated and evolved into the average penguin and giraffe we know today.

1.) The term means "terrible lizard", derived from Greek words. Extremely successful creatures who are believed to have died out 65 million years ago and lived/ruled during the Mesozoic era. Some (meaning the theropods) are also believed to be the ancestors of modern-day birds due to feather imprints around fossils and other similarities, with the closest links being the dromaeosaurs (raptors); however, none seem to have been able to actually fly.

There were a number of different groups, but they are generally classified by whether they were herbivorous or carnivorous, which is also also by the structure of their hip bones (bird- or lizard-hipped). Some, if not all, might have even been warm-blooded. They were also the descendants of reptiles, not the other way around. And contrary to popular belief, most were not ridiculously huge. Most were were about the size of a large car or smaller.

Although it seems like we've dug up every dinosaur that ever lived in the world, in truth it is only a small percentage, so we'll never actually really know that much about them. Oh, and don't forget that thanks to World War II, the first fossils of Carcharodontosaurus and Spinosaurus were destroyed.

2.) Something old or outdated; obsolete. May also pertain to the description of an older person.
When the fossils of a dinosaur called Megalosaurus were found in 1677, people thought it was a dragon.

Really big bloody reptile thing that used to live a long long time ago and they ate eachother and said "rawr!". Sometimes there were boring dinosaurs that were small and/or ate plants because they sucked. However some of them could fly and stuff, which was awesome. They also said "rawr".
Dinosaur 1: "I am going to eat you all up! Rawr!"
Dinosaur 2: "Oh no!"

Adding "...and did the dinosaur" to the very end of any long winded supposedly interesting or scary story to piss people off.
As he got off the train he realized he had one choice. Death. So he dropped to the floor and did the dinosaur!
