根据一具不完整的骨架，描述了威尔切克岛(Franz Josef Land)上三叠统下-中诺利统(Wilczek组)的一新属一种--Alexeyisaurus karnoushenkoi。新的形态结合了典型晚期蛇颈龙的特征和该形态特有的结构特征。它可能是典型的晚期翼龙(蛇颈龙)的最早代表。
A new elasmosaurid genus and species, Alexeyisaurus karnoushenkoi, from the Lower-Middle Norian (Wilczek Formation) of the Upper Triassic of the island of Wilczek Land (Franz Josef Land) is described based on an incomplete skeleton. The new form combines characters of typical late plesiosaurs and structural features unique to this form. It is probably the earliest representative of typical late sauropterygians (plesiosaurs).
