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.

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

No modern animal has two brains, unless it is a conjoined animal with two heads as a result of incomplete twin formation. The stegosaurus, a large plant-eating dinosaur, was thought to have had two brains, but paleontologists now believe the second cranial cavity was for fat storage.

No. A monkey does not have two brains, only one as in apes and primates. No extant mammal has two true brains.
