UDANOCERATOPS

At an estimated four meters in length, Udanoceratops — Udan Sayr horn face — is the biggest non-ceratopsid neoceratopsian discovered thus far, and bearing in mind the only known adult remains amount to a skull and a far from complete skeleton it could turn out to be bigger.

It is the first Asian representative of Leptoceratopsidae - a branch of ceratopsian ("horn faced") herbivores with a distinct lack of face horns and precious little in the way of a frill, though it did have an astoundingly deep and robust, curved lower jaw and parrot like-beak, probably for nipping needles and leaves from tough ferns, cycads and conifers.

With proportionately long hind legs, paleontologists suspect Udanoceratops was bipedal, but some experts have mused that its deep "rudder-like" tail, formed by long spines on its vertebrae, may have been an adaptation for a semi-aquatic lifestyle. This is a feature shared with Koreaceratops, Montanoceratops, Protoceratops and Bagaceratops.
