Funiusaurus luanchuanensis gen. et sp. nov. was described on the basis
of an incomplete skull from the Upper Cretaceous Qiupa Formation of
the Tantou Basin in Luanchuan County, Henan Province. It is the second
representative of lizards known from Luanchuan and adds a new member
to the Luanchuan Fauna. F. luanchuanensis is a small-sized lizard and
systematically assigned to the Polyglyphanodontidae of the Teiioidea
because of the presence of a caniniform tooth and an elongate
posterior process of the postorbital. It is distinctive in that the
heterodont dentition bears 19 teeth in both the upper and lower jaws,
the 3rd maxillary tooth is large and caniniform, the post-caniniform
teeth in maxilla and those posterior to the 3rd dentary tooth are
chisel-like in lateral view, the prefrontal possesses a fossa on its
lateral surface, the postorbital with an extremely elongate posterior
process and the well-developed retroarticular process has a deep fossa
on its dorsal surface. In phylogeny, our analysis suggests a close
relationship of Funiusaurus to the large-sized Tianyusaurus from the
same basin within the Tuberocephalosaurinae. The discovery of
Funiusaurus is significant in confirming the status of the
Tuberocephalosaurinae, which includes a group of the Asian members of
the Polyglyphanodontidae only.
