Pterorhynchus ("wing snout") is an extinct genus of pterosaur from the mid-Jurassic aged Yanliao Biota[1] of Inner Mongolia, China.
The genus was named in 2002 by Stephen Czerkas and Ji Qiang. The type species is Pterorhynchus wellnhoferi. The genus name is derived from Greek pteron, "wing" and rhynchos, "snout", in reference to the tall crest on the head. The specific name honours the German pterosaur researcher Peter Wellnhofer.
The genus is based on holotype CAGS02-IG-gausa-2/M 608 (earlier DM 608). It was found in Chifeng in the Daohugou Beds. According to Ji Pterorhynchus belongs to the Yanliao Biota from the Haifanggou Formation of the Callovian; Lü Junchang in 2007 ascribed it to the somewhat later Tiaojishan Formation of the same stage. In 2023, it is suggested that taxon is from Haifanggou Formation again.[2]
