In the eastern Canadian province of Nova Scotia, scientists have unearthed prosauropods from the McCoy Brook Formation, which is about 200 to 197 million years old, from the Early Jurassic Hettangian stage. The Nova Scotia material provides clues about the diet of these animals. A large number of gastroliths, stones swallowed to grind up plant material in the gut, were found in the abdomen, as well as bone from the skull of a small sphenodont, "Clevosaurus". This indicates that these dinosaurs were omnivorous, with a diet mainly consisting of plants but with an occasional supplement of meat. However, these remains have never been fully described or illustrated and were only tentatively referred to "Ammosaurus". A further study identified them as a new taxon of sauropodomorph, "Fendusaurus eldoni".
