Abstract
A new assemblage of thalattosaurs is described from the Lower to Middle Triassic Sulphur Mountain Formation of eastern British Columbia. The following new species are described: Thalattosaurus borealis n. sp.; Paralonectes merriami n. gen. and sp.; and Agkistrognathus campbelli n. gen. and sp. In addition, specifically indeterminate material is described. This assemblage extends the geographic range of the Thalattosauria to Canada and demonstrates that thalattosaurs were more taxonomically diverse and widely distributed than previously thought.Keywords
