Publication History


Brachiosaurus was one of the biggest animals that has ever lived. Its front legs were longer than its hind legs giving Brachiosaurus a more upright stance than most sauropods. This dinosaur could raise its head almost forty feet off the ground and must have looked like a titanic, reptilian giraffe. However, since Brachiosaurus lived over a hundred million years before the first giraffe appeared, it may be more appropriate to say that giraffes are tiny, mammalian versions of Brachiosaurus!

The figure of a six-foot tall man helps illustrate how immense this creature was.
