New long-tailed pterosaurs (Wukongopteridae) from western Liaoning, China

Two almost complete long-tailed pterosaurs from the Linglongta, Jianchang County, western Liaoning, China, are described and represent new taxa referred to the non-pterodactyloid clade Wukongopteridae. Kunpengopterus sinensis gen. et sp. nov. differs from other members of this clade mainly by the ro...

description Two almost complete long-tailed pterosaurs from the Linglongta, Jianchang County, western Liaoning, China, are described and represent new taxa referred to the non-pterodactyloid clade Wukongopteridae. Kunpengopterus sinensis gen. et sp. nov. differs from other members of this clade mainly by the rounded posterior region of the skull, thick lacrimal process of the jugal and lack of a bony premaxillary crest. This species further shows a soft tissue crest above the frontal, a comparatively larger wing finger, and the proximal segment of the second pedal phalanx of the fifth toe shorter than in other wukongopterids. The second new species is referred to the genus Darwinopterus, D. linglongtaensis sp. nov. based on the posterior region of the skull. It further differs from other wukongopterid pterosaurs by the thin lacrimal process of the jugal, foramen on nasal process rounded, and by having the second pedal phalanx of the fifth toe less curved (115°). Several differences among the Wukongopteridae can be found in the dentition and the feet, suggesting that they might have occupied slightly different ecological niches. The long-tailed Changchengopterus pani is tentatively referred to this clade and new diagnosis for the wukongopterids Wukongopterus lii and Darwinopterus modularis is provided.<br>Dois novos pterossauros de cauda longa procedentes de Linglongta, Jianchang County da região oeste de Liaoning, China, são descritos e referidos ao clado Wukongopteridae. Kunpengopterus sinensis gen. et sp. nov. difere dos demais integrantes desse clado basicamente pela região mais arredondada da parte posterior do crânio, pelo espesso processo lacrimal do jugal e pela ausência de uma crista óssea premaxilar. Esta espécie apresenta uma crista formada por tecido mole acima da região frontal e possui o dedo alar proporcionalmente maior do que nos demais wukongopterídeos. A segunda espécie é referida ao gênero Darwinopterus, D. linglongtaensis sp. nov., com base na região posterior do crânio. Difere dos deais pterossauros wukongopterídeos por possuir o processo lacrimal do jugal delgado, o forâmen no processo nasal arredondado e pela condição menos curvada da segunda falange do quinto dígito do pé. As principais diferenças entre os Wukongopteridae são encontradas na dentição e nos pés, o que sugere que estes ocupavam nichos ecológicos ligeiramente distintos. O pterossauro de cauda longa Changchen-gopterus pani também é tentativamente referido a esse clado. Novas diagnoses para os wukongopterídeos Wukongopterus lii e Darwinopterus modularis são apresentadas.
