sauropterygian from the Upper Triassic of Wilczek Land (Franz Josef
Land, Arctic Russia). Paleontological Journal 44 (5): 567-572. 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).
