Pterorhynchus Wellnhoferi
''Pterorhynchus'' ("wing snout") is an extinct genus of pterosaur from the mid-Jurassic aged Daohugou Formation of Inner Mongolia, People's Republic of China, 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 (zoology), 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.

Middle Jurassic
The Middle Jurassic is the second epoch of the Jurassic Period. It lasted from about 174.1 to 163.5 million years ago. Fossils of land-dwelling animals, such as dinosaurs, from the Middle Jurassic are relatively rare, but geological formations containing land animal fossils include the Forest Marble Formation in England, the Kilmaluag Formation in Scotland,British Geological Survey. 2011Stratigraphic framework for the Middle Jurassic strata of Great Britain and the adjoining continental shelf: research report RR/11/06 British Geological Survey, Keyworth, Nottingham. the Daohugou Beds in China, the Itat Formation in Russia, and the Isalo III Formation of western Madagascar. Paleogeography During the Middle Jurassic Epoch, Pangaea began to separate into Laurasia and Gondwana, and the Atlantic Ocean formed. Eastern Laurasia was tectonically active as the Cimmerian plate continued to collide with Laurasia's southern coast, completely closing the Paleo-Tethys Ocean. A subduction zone ...
