10 Interesting Facts About Dinosaurs: Did You Know?

Scientists first started studying dinosaurs during the 1820s, when they discovered the bones of the biggest land reptile they named a Megalosaurus (“big lizard”) buried in the English countryside. In 1842, Sir Richard Owen, top paleontologist of Britain, first introduced the term “dinosaur.”

Owen hcave-dinosaurs-skeletonad initially examined the bones from three unique creatures– Iguanadon (“iguana tooth”), Megalosaurus, and Hylaeosaurus (“woodland lizard”). Each one of them lived on land, was bigger than any living reptile, walked with their legs directly under their bodies instead of out to the sides and had three additional vertebrae in their hips compared to other known reptiles.

Using this information, Owen realized that the three formed a special group of reptiles that he named Dinosauria. The word comes from the old Greek word deinos (“terrible”) and sauros (“reptile” or “lizard”).

Dinosaurs survived for over 700,000 years after the earth was hit by a huge meteorite initially believed to have resulted in their extinction, according to new research.

Dinosaurs wandered the Earth more than 200 million years ago and were the very dominant terrestrial vertebrate for 135 million years. It is believed their extinction was as a result of variations in the climate they could not adapt to. Birds are the only closest relative of a dinosaur which we have today.

Dinosaur is a topic many people feel they have some knowledge of it. After all, almost everyone has seen or heard of the blockbuster movie Jurassic Park, and young kids are often the experts in any house on the names, sizes, shapes, and eating characters of these ancient reptiles.

Honestly, several people can tell you that dinosaurs were really huge, and that some of them had feathers, and that they became extinct 65 million years ago. But how deep does their knowledge of Mesozoic Era, and the dinosaurs, really go?
