|When people hear the word "dinosaur", many think of the long-necked Sauropods. The most famous of these was called "Brontosaurus", but it was discovered that brontosaurus fossils were the same as those of a previously named dinosaur: APATOSAURUS. Apatosaurus was heavy, with a long muscular neck and elephant-like legs. It had a long whiplike tail that may have been used as a defense against large predators. It also had a sharp claw on each thumb that may have deterred attackers. Possibly traveling in herds, these dinosaurs had to eat a lot of food to keep their massive bodies going. They may have swallowed plant matter whole and ground it up with a gizzard, much as birds do today.
