"They might be social creatures, look, there are so many of them here. One by one, the Kentrosaurus has a very small head, so it isn't too intelligent. Its most famous—and most beloved—feature is the large bony plates spread across its spine and the four spike-like ridges on its tail."
"The most distinct characteristic on the outside is the row of triangular bone plates along its back and the four spikes on its tail. The massive Kentrosaurus has an extremely small head, even smaller than that of a small dog's brain, so scientists believe they were quite a dumb species of dinosaurs."
"Some speculate that the Kentrosaurus might have had two brains: one in its tiny head, and another in its buttocks. The one in the head was the 'main brain,' while the one in the rear was the 'auxiliary brain.' The two brains worked together to enable the Kentrosaurus to adapt to its complex living environment."
