Homalocephale, a fairly small dinosaur, was discovered in 1969 in Mongolia. This was the only member of this bone-headed family that had been found with a body and skull until a 1996 discovery of an almost complete pacycephalosaur.

This dinosaur is another example of families of dinosaurs spreading between North America and Asia that evolved as they migrated. The design of this dinosaur's mouth seems to indicate it was a plant-eater.
