Hamipterus is an extinct genus of pteranodontoid pterosaurs from the Early Cretaceous Shengjinkou Formation of northwestern China.

[2] In 2006 from the Hami region in Xinjiang, the Shengjinkou Formation, a Konservat-Lagerstätte was reported, in this case lake sediments allowing for an exceptional preservation of fossils.

Part of the finds consisted of dense concentrations of pterosaur bones, associated with soft tissues and eggs.

[2] In 2014, the type species Hamipterus tianshanensis was named and described by Wang Xiaolin, Alexander Kellner, Jiang Shunxing, Wang Qiang, Ma Yingxia, Yahefujiang Paidoula, Cheng Xin, Taissa Rodrigues, Meng Xi, Zhang Jialiang, Li Ning, and Zhou Zhonghe.

Together, they comprise the remains of at least 40 animals, both bones and soft tissue remnants such as the horn sheaths of skull crests.

The finds in 2014 represented the largest known concentration of pterosaur fossils, with the exception of the Pterodaustro nesting colonies of Argentina.

[3] Hamipterus Iberodactylus Tropeognathus Coloborhynchus Siroccopteryx Uktenadactylus Caulkicephalus Guidraco Ludodactylus Anhanguera Liaoningopterus Cearadactylus Maaradactylus The large number of individuals found allowed the establishment of a growth series, showing how individuals developed through their ontogeny.

No change, however, takes place in the number of teeth, the degree of fusion in the symphysis of the lower jaws, or the shape of the postcranial skeleton, as far as can be ascertained, given the fact that the elements behind the skull were not found articulated.

With the close proximity of the nests and adults, as well as how underdeveloped the hatchlings were for flying, it has also been suggested that Hamipterus practiced some form of parental care.

[5] A 2021 further disagrees by demonstrating that the young of Hamipterus don't differ significantly from the other flight capable flaplings.
