- Period/Epoch: Cretaceous / Late Cretaceous
- Rock Formation: Lance Formation
- State, County: Unknown
Taxonomy: Dinosauria>Ornithischia>Pachycephalosauridae>Pachycephalosaurus wyomingensis
Pachycephalosaurs were ornithischian dinosaurs from the Cretaceous of North America and Asia. They are a sister group to the ceratopsians, and are characterized by very thick skull domes, which are the most common part of them preserved in the fossil record due to their size and thickness. The growth cycle of pachycephalosaurs is unclear due to the lack of these domes in the smaller genera, and it is generally presumed that the domes grew over the lifespan of the animal. There has been many studies done on the potential purpose and targets of these domes, and many have been found with significant head wounds. This specimen shows the top of a head dome.
