Why is the existence of Xenoceratops vital to paleontology regarding North American ceratopsians?
Answer
It is the oldest known large-bodied ceratopsid fossil identified from Canada
The significance of *Xenoceratops* to the study of paleontology lies primarily in its geological age and geographic location relative to other large ceratopsids. It represents the oldest known large-bodied ceratopsid fossil discovered in Canada, with its rock layers dating between 80.3 to 79.5 million years ago. This temporal placement is crucial because it offers insight into the initial radiation and diversification event of large ceratopsians in North America, appearing several million years before more derived, giant forms arrived on the scene.
