A: Being large can help you defend yourself against predators, can help you obtain prey, can conserve heat, may sometimes help in attracting a mate, and may help in getting a superior social position (this is true for some social animals). There are also drawbacks to being big, especially the need to eat so much. It isn't known exactly why some of the dinosaur got so big.

A: Estimates of megalodon's length vary quite a bit - it was about 40 feet (12 m) long or perhaps even more. It probably looked a lot like a huge, streamlined great white shark. For a page on megalodon, click here.

A: No, the blue whale is more massive (it weighs more) than any dinosaur, but many sauropod dinosaurs were longer that its 100 ft length.

A: Unfortunately, no Megaraptor thigh bones (femurs) from have been found yet. Only claws, an arm bone, some foot bones, and finger bones have been found.
