Ceratopsid

Behavior

Other researchers who support the idea of ceratopsid herding have speculated that these associations were seasonal. This hypothesis portrays ceratopsids as living in small groups near the coasts during the rainy season and inland with the onset of the dry season. Support for the idea that ceratopsids formed herds inland comes from the greater abundance of bonebeds in inland deposits than coastal ones. The migration of ceratopsids away from the coasts may have represented a move to their nesting grounds. Many African herding animals engage in this kind of seasonal herding today. Herds would also have afforded some level of protection from the chief predators of ceratopsids, tyrannosaurids.
