Alexeyisaurus

Alexeyisaurus is an extinct genus of possible plesiosaur known from the upper Triassic (lower-middle Norian age) of Wilczek Formation, Wilczek Land, of Franz Josef Land, Russia.[1] It was first named by A. G. Sennikov and M. S. Arkhangelsky in 2010 and the type species is Alexeyisaurus karnoushenkoi.[1] While considered an elasmosaur in the initial publication It has been described as a "partial, poorly preserved, and undiagnostic sauropterygian skeleton" in subsequent publications.[2]
