Dsungaripterus is a genus of dsungaripterid pterosaur with an average wingspan of 3 meters (9.8 ft).[1] Dsungaripterus lived during the Early Cretaceous in what is now China, and its first fossil was found in the Junggar Basin.

Description[edit]

Restoration of Dsungaripterus (above) and the related Noripterus

Dsungaripterus weii had a wing span of 3 to 3.5 meters (9.8 to 11.5 ft). Like most dsungaripteroids it had a rather robust skeleton with thick walls and stouty bodily proportions, suggesting a mostly terrestrial lifestyle. The flight style of these animals is unclear, but it was probably punctuated by abrupt landings and extensive flapping.[2]

The skull of Dsungaripterus, 40 to 50 centimeters (16 to 20 in) long, bore a low bone crest that ran down from the base of the skull to halfway to the beak. Dsungaripterus's head and neck were together almost 1 meter (3.3 ft) long. Its most notable feature are its long, narrow, upcurved jaws with a pointed tip. It had no teeth in the front part of its jaws, which were probably used to remove prey from cracks in rocks and/or the sandy, muddy inland environments it inhabited. It had knobbly flat teeth more to the back of the jaw that were well suited for crushing the armor of shellfish or other hard objects.[1]

Dsungaripterus also had a palate similar to that of azhdarchoid pterosaurs.[3]

History of discovery[edit]

Dsungaripterus was described in 1964 named by Yang Zhongjian. The genus name combines a reference to the Junggar Basin with a Latinized Greek pteron, "wing". The type species is Dsungaripterus weii, the specific name honoring paleontologist C.M. Wei of the Palaeontological Division, Institute of Science, Bureau of Petroleum of Xinjiang. The holotype is IVPP V-2776, a partial skull and skeleton. From 1973 more material has been found including almost complete skulls.

In 1980 Peter Galton renamed Pterodactylus brancai (Reck 1931), a form from a late Jurassic African formation, into Dsungaripterus brancai, but the identification is now commonly rejected. In 1982 Natasha Bakhurina named a new species, Dsungaripterus parvus, based on a smaller skeleton from Mongolia. Later, this was renamed into "Phobetor", a preoccupied name, and in 2009 concluded to be identical to Noripterus. In 2002 a Dsungaripterus wing finger phalanx was reported from Korea.

Classification[edit]

Skeletal restoration

Dsungaripterus was classified by Yang as a member of the Dsungaripteridae. Below is a cladogram showing the phylogenetic placement of Dsungaripterus within the clade Neoazhdarchia. The cladogram follows a topology recovered by Brian Andres and Timothy Myers in 2013.[4]
