Stegoceras, a genus of dinosaur known for its thick, domed skull, likely used its head as a weapon during confrontations. It may have engaged in head-butting behavior similar to modern-day animals like bighorn sheep, using its robust skull to deliver powerful blows to rivals during mating displays or territorial disputes. This behavior would have been facilitated by its strong neck muscles, allowing it to assert dominance and compete for mates.

One, and it's about the size of a walnut. Actually, scientists thought for a while the stegasaurus may have had a brain-like structure in it's tail. The expansion of the spinal column in the pelvis gave rise to the incorrect idea that dinosaurs had two brains. Yes, the size of a walnut!
