Megalosaurus was the first dinosaur that was described as a reptile. This dinosaur is often described as being part of the "waste bucket" genus because so many bones from other dinosaurs have been mistaken for being that of the Megalosaurus!
Diplodocus was an incredibly large dinosaur. It is the longest dinosaur known from complete skeletons. A fully grown adult could reach a length of 90 feet. Skeletons of this massive dinosaur have been found in North America.
