"Fendusaurus" is a naked genus of prosauropod dinosaur that lived in Nova Scotia during the Early Jurassic.
Description[]
"Fendusaurus" is known from a dissertation by Timothy J. Fedak (2006), which proposes the name to represent a skull, FGM998GF13-II. Found by a team from Princeton University, referred specimen include: FGM998GF13-I, FGM998GF13-III, FGM998GF69, FGM998GF9 and FGM998GF18. These include femora and coracoids, which differ, but are credited as intraspecific variation. They were once attributed to cf. Ammosaurus. These femora and coracoids help identify individuals, with Fedak finding each block represents at least one individual. It is known from the Hettangian-aged McCoy Brook Formation, Wasson Bluff, Nova Scotia. This is the richest sauropodomorph site in North America, which is similar to other North American and Asian formations, lacking any Anchisaurus. It was assigned to Massospondylidae.
All specimens include somewhat crushed vertebrae with appendicular material. They distinguish from Anchisaurus due to ilium and sacral vertebrae morphology. Fedak also speculates several species may have been present based on the femora and coracoids. Extreme cervical vertebrae elongation, four-vertebrae sacrum that has a dorsosacral and caudosacral, an elongate postacetabular process on the ilium and an expanded anterior distal process on the tibia distinguish it from sauropodomorphs.
