Dsungaripterus is a genus of dsungaripterid pterosaur which lived during the Early Cretaceous in what is now China and possibly South Korea. Its first fossil was found in the Tugulu Group (Lianmuqin and Shengjinkou Formations) of the Junggar Basin.

Dsungaripterus weii had a wingspan of 3–3.5 metres (9.8–11.5 ft). [1] 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, measuring over 46 centimeters (18 in) long, [3] 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. [4] Thus, it is commonly interpreted that dsungarupterids were durophagous and possibly piscivorous pterosaurs. [5] Additionally, Dsungaripterus also had a palate similar to that of azhdarchoids. [3]

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 the Lianmuqin Formation. [1] In 1973, more material has been found within the Shengjinkou Formation, which includes almost complete skulls. [6]

In 1980 Peter Galton renamed Pterodactylus brancai (Reck 1931) from the Tendaguru Formation into Dsungaripterus brancai, but the identification is now commonly rejected. [7] 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 . A dsungaripterid wing finger phalanx was reported in 2002 from the Hasandong Formation of South Korea, [8] and was identified in 2015 and 2018 as Dsungaripterus? cf. D. weii. [9] [10]

Dsungaripterus was classified by Yang as a member of the Dsungaripteridae. Below is a cladogram showing the results of a phylogenetic analysis presented by Andres and colleagues in 2014. They recovered Dsungaripterus within the clade Dsungaripteromorpha (a subgroup within the Azhdarchoidea), more specifically within the Dsungaripteridae, sister taxon to Domeykodactylus . Their cladogram is shown below. [11]

Dsungaripteromorpha

In 2019, a different topology, this time by Kellner and colleagues, was published. In this study, Dsungaripterus was recovered outside the Azhdarchoidea, within the larger group Tapejaroidea, sister taxon to Noripterus. The cladogram of the analysis is shown below. [12]

Azhdarchidae is a family of pterosaurs known primarily from the Late Cretaceous Period, though an isolated vertebra apparently from an azhdarchid is known from the Early Cretaceous as well. Azhdarchids are mainly known for including some of the largest flying animals discovered, but smaller cat-size members have also been found. Originally considered a sub-family of Pteranodontidae, Nesov (1984) named the Azhdarchinae to include the pterosaurs Azhdarcho, Quetzalcoatlus, and Titanopteryx. They were among the last known surviving members of the pterosaurs, and were a rather successful group with a worldwide distribution. Previously it was thought that by the end of the Cretaceous, most pterosaur families except for the Azhdarchidae disappeared from the fossil record, but recent studies indicate a wealth of pterosaurian fauna, including pteranodontids, nyctosaurids, tapejarids and several indeterminate forms. In several analyses, some taxa such as Navajodactylus, Bakonydraco and Montanazhdarcho were moved from Azhdarchidae to other clades.

Batrachognathus is an extinct genus of anurognathid pterosaur from the Late Jurassic Karabastau Formation of the central Asian republic of Kazakhstan. The genus was named in 1948 by the Russian paleontologist Anatoly Nicolaevich Ryabinin. The type species is Batrachognathus volans. The genus name is derived from Greek batrakhos, "frog" and gnathos, "jaw", in reference to the short wide head. The specific epithet means "flying" in Latin.

The full binomial of the taxon is Linlongopterus jennyae, with the generic name translating from the Chinese "forest" (lin) and "dragon" (long), and the Greek "wing" (pteros), while the species name honours Elfriede Kellner, nicknamed Jenny, a supporter of paleontology. The proper word for wing in ancient Greek is however pteron (πτερόν).
