Noripterus (meaning "lake wing" from Mongolian nuur, "lake" and Greek pteron, "wing") is a genus of dsungaripterid pterodactyloid pterosaur from Lower Cretaceous-age Lianmuqin Formation in the Junggar Basin of Xinjiang, China. It was first named by Yang Zhongjian (also known as C.C. Young in older sources) in 1973. Additional fossil remains have been recovered from Tsagaantsav Svita, Mongolia.


The first, holotype specimen of Noripterus (IVPP V.4062, type locality IVPP 64045) preserved the front part of the skull and lower jaws, vertebrae, and partial limbs and pelvis. Noripterus was quite similar to the contemporaneous Dsungaripterus, though it was estimated to be a third shorter. It has long narrow neck vertebrae and, like Dsungaripterus, a crest and no teeth in the front of the lower jaw. The teeth that are present are well-developed and spaced fairly far apart. The sharp snout is straight and not pointed upwards as with Dsungaripterus.


Because of its similarity to Dsungaripterus, Noripterus has been assigned to the family Dsungaripteridae.[2]

The genus Phobetor, named after the Greek god of nightmares, was in 1982 originally described by Natasha Bakhurina as a species of Dsungaripterus (D. parvus), based on a single lower leg bone, PIN 3953. The discovery of more remains later, among which an almost complete skull, GIN 100/31, was reason for Bakhurina to name D. parvus in 1986 as a separate genus, and the species name became Phobetor parvus. However, the genus name Phobetor was already being used as a junior synonym of a species of sculpin, namely, the arctic staghorn sculpin, Gymnocanthus tricuspis (synonym "Phobetor tricuspis" Krøyer, 1844) and thus unavailable. In 2009, Lü and colleagues re-examined much of the known dsungaripterid fossil material, and found that "Phobetor" was indistinguishable from Noripterus, causing them to refer to it as a junior synonym.[3]

Assigning the "Phobetor" material to Noripterus increases the known size of the latter as it indicates a maximum wingspan of 4 metres (13.1 ft).
