The two brain idea can be found in many older dinosaur books, although
it is usually associated with stegosaurs, rather than brachiosaurs.
When dino skeletons were first being mounted it was noticed that some
had what seemed to be unusually large spinal cord openings in the sacral
vertebra (over the hips). This was interpreted to mean that there was a
large nerve center located here. As most dino braincases are considered
quite small by mammalian standards, the idea developed that these huge
animals would need a second "brain" to control the bulky rear portion.
This enlarged neural area has been recognised as a large nerve junction
similar to those found in human shoulder and hip areas. Dinosaurs had
to get along with one brain, just like the rest of us. Someday the
outdated dino books will all be replaced with more current sources of
Hope this helped answer some questions.
