Paleontologists now realize that what they thought was a second brain was an enlargement in the spinal cord in the hip area, perhaps containing fat and nerve tissue. This nerve center may have controlled the animal's hind legs and tail and was larger than the animal's tiny brain.

Some dinosaurs, like the Stegosaurus, had a small second brain near their hips that helped coordinate movement in their hind legs. This second brain acted almost like a reflex center. It wasn't a full brain like the one in their skull, but it helped improve their coordination.

Scientists thought that some dinosaurs may have had two brains. However, it may have been a medical condition where the spinal cord was enlarged.
