Research Abstract

An exquisite plesiosaurian fossil from the Upper Cretaceous in Manitoba Escarpment, Canada, was described and compared with related taxa, and a 3D reconstruction of the braincase. Field and museum survey revealed the presence of diverse plesiosaurian fossils, indicating the academic importance of the escarpment for the study of Late Cretaceous marine reptiles.
