In Depth Since the genus was named in 2003, there has been some speculation that Lamaceratops may in fact be based upon fossils referable to Bagaceratops. This is because there is very little difference between known fossils of Bagaceratops and the holotype fossils for Lamaceratops, though Lamaceratops may also represent a species of Bagaceratops not … Read more
