incipient cavities in the skull roof. Classification Turanoceratops belonged to the Ceratopsia (the name is Greek for "horned face"), a group of herbivorous dinosaurs with parrot-like beaks which thrived in North America and Asia during the Cretaceous Period, which ended 66 million years ago. All ceratopsians became extinct at the end of this period. A 2009 study led by Hans-Dieter Sues analysed additional fossil material of Turanoceratops and concluded that, contrary to expectations, it represented a true (though "transitional") member of the family Ceratopsidae. If correct, it would represent an Asian ceratopsid. At the time of publication this would have been unique, as all other ceratopsids known to that point were from North America. Some scientists, such as Andrew Farke, disagreed with Sues' findings. Farke and colleagues ran an independent phylogenetic analysis of the new Turanoceratops fossils and found that it was a close relative of Ceratopsidae (the immediate sister group) but was not a true member of that clade. Sues and Alexander Averianov criticised that analysis, arguing that Farke and colleagues misinterpreted or mis-coded some characteristics of the fossil in their analysis. However, Xu et al. (2010) conducted a phylogenetic analysis and concluded that Turanoceratops was more derived than Zuniceratops and was outside of Ceratopsidae, because it lacks several important synapomorphies of this group. Paleobiology Turanoceratops, like all ceratopsians, was a herbivore. During the Cretaceous, flowering plants were "geographically limited on the landscape", and so it is likely that this dinosaur fed on the predominant plants of the era: ferns and conifers. It would have used its sharp ceratopsian beak to bite off the leaves or needles.
