Apatosaurus is perhaps one of the most famous dinosaurs because of the size of the animal. A fully grown Apatosaurus could reach up to 70 feet in length. The size of this dinosaur is what earned it the nickname "thunder lizard."
Acrocanthosaurus was a sauropod of spectacular proportions. In some ways it looked like many other meat-eating dinosaurs, but it had a sail along its back. See pictures and learn more about this dinosaur.
