To which major dinosaur family does *Xenoceratops* belong based on its horned, frilled head structure?
Answer
Ceratopsidae
*Xenoceratops* shares the distinctive physical characteristics of a horned and frilled head structure that links it directly to the Ceratopsidae family. This family encompasses the group recognized for these elaborate cranial features, including the more famous three-horned dinosaurs. Understanding this familial placement is fundamental to tracing the evolutionary path and diversification patterns of horned dinosaurs across the North American continent during the Late Cretaceous period, as its position within the strata helps define its evolutionary relationships relative to other members of this family.
