A nearly complete skull of a new ctenochasmatid pterosaur, Pterofiltrus 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.
Note: The name is misspelled in the actual abstract and key words as
"Pterofiltus" but is officially Pterofiltrus in the body of the paper.
