About Prenocephale:
You might not be surprised to learn that pachycephalosaurs ("thick-headed lizards") are often represented in the fossil record only by their massive skulls. To date, that's the case with Prenocephale; the rest of this herbivore has been reconstructed with reference to closely related boneheads such as Homalocephale and Tylocephale.
The abiding mystery about pachycephalosaurs is why they had such thick skulls. Many paleontologists believe the males head-butted each other for the favor of females, but some hold to the view that boneheads used their thickened noggins to butt the flanks of other dinosaurs, since a full-on collision might well have been fatal.
