With its dome-shaped head, the aptly named “thick-headed lizard” Pachycephalosaurus lived in the late Cretaceous period. Measuring about 15 feet long, it is hypothesized that these dinosaurs may have used their heads for ramming into the flanks of their rivals; another theory, running headlong into each other, is less likely based on the shape of their necks.
