Abstract

The last (IX) cervical vertebra from the Upper Cretaceous (Campanian) coastal marine deposits of Izhberda Quarry near the town of Orsk (Orenburg oblast) belonged to a large pterosaur with an estimated wingspan of 5.6 m. This vertebra is most similar to the IX cervical vertebra of a giant pterosaur Quetzalcoatlus sp. from the Maastrichtian of the United States in the relatively long centrum and the large hypapophysis and identified as Azhdarchidae indet. This finding is the first evidence of the existence of giant Azhdarchidae pterosaurs on the territory of Russia.

摘要

位于奥尔斯克镇（奥伦堡州）附近的 Izhberda 采石场的上白垩纪（坎帕尼亚）沿海海洋沉积物中的最后一块（IX）颈椎属于一种大型翼龙，估计翼展为 5.6 m。该椎骨与巨型翼龙Quetzalcoatlus sp 的 IX 颈椎最相似。来自美国马斯特里赫特人在相对较长的中心和大的垂体中，被鉴定为Azhdarchidae indet。这一发现是俄罗斯境内存在巨型翼龙科翼龙的第一个证据。
