Wolfville Formation

The Wolfville Formation is a Triassic geologic formation of Nova Scotia. The formation is of Carnian to early Norian age.[2] Fossils of small land vertebrates have been found in the formation, including procolophonid and early archosauromorph reptiles and cynodonts. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.[3]
