Dinosaurs once ruled Earth and we're continually learning more about them. You might know of the T. Rex and the Triceratops, but have you heard of the duck-billed Edmontosaurus or the peacock-like Nomingia?

From raptors to tyrannosaurs and sauropods to ornithopods, this list includes every dinosaur that has ever lived. It spans the Triassic, Jurassic, and Cretaceous periods and includes interesting facts about each dinosaur. You'll find it to be hours of fun and there's a new dinosaur waiting for you to discover.


Watch Now: 9 Fascinating Dinosaur Facts

A to D Dinosaurs

Within these first dinosaurs, you will find well-known names like the Brachiosaurus, Brontosaurus, and the Apatosaurus (formerly the Brontosaurus). There are also interesting dinosaurs like the Argentinosaurus which is thought to have been the largest dinosaur ever to live and the Dromiceiomimus, which may have been the fastest.

You can also get a hint at how paleontologists have fun when naming dinosaurs. For instance, the Bambiraptor was a tiny raptor named for Walt Disney's famous deer and the Dracorex got its name from the "Harry Potter" books.
