Gobiazhdarcho

Gobiazhdarcho () is an extinct genus of azhdarchid pterosaurs known from the Late Cretaceous Bayanshiree Formation of Mongolia. The genus contains a single species, Gobiazhdarcho tsogtbaatari, known from a three cervical (neck) vertebrae. It was closely related to Quetzalcoatlus and coexisted with Tsogtopteryx, another azhdarchid more closely related to Hatzegopteryx.

== Discovery and naming == thumb|left|Mongolian Cretaceous fossil localities; Gobiazhdarcho is known from the Burkhant locality in Area D (Bayanshiree Formation) In 1995, a joint paleontological expedition between the Hayashibara Museum of Natural Sciences and the Mongolian Paleontological Center conducted fieldwork in the Gobi Desert of Mongolia. At the 'Burkhant' locality of the Bayanshiree Formation in Dornogovi Province, workers collected three associated cervical (neck) vertebral elements. These specimens, accessioned as MPC−Nd 100/302, include the atlantoaxis (fused first and second cervicals), the third cervical, and the posterior (back) part of the sixth cervical (identified as the fourth by Averianov in 2014). In 2009, Mahito Watabe and colleagues described this specimen, in addition to another isolated pterosaur cervical vertebra from the 'Bayshin Tsav' locality of the same formation. The authors refrained from naming either specimen, but discussed their anatomy and likely phylogenetic affinities in depth.
