JIANG, Shunxing and WANG, Xiaolin. A new ctenochasmatid pterosaur from the Lower Cretaceous, western Liaoning, China. An. Acad. Bras. Ciênc. [online]. 2011, vol.83, n.4, pp. 1243-1249. ISSN 0001-3765. http://dx.doi.org/10.1590/S0001-37652011000400011.
A nearly complete skull of a new ctenochasmatid pterosaur, Pterofiltus qiui gen. et sp. nov., from the Lower Cretaceous deposits of Liaoning, China, is described here. The specimen (IVPP V12339), was collected from the shale of the lower Yixian Formation (125 Ma) at the Zhangjiagou locality. It has the following combination of characters: about 112 teeth in total (including the upper and lower jaws); the dentition occupies more than 50% of the skull length; the anterior teeth vary in size; the mandibular symphysis is longer than half of the whole mandible length; in ventral view, an apparent symphyseal trough in the median part of the symphysis.
