The unusual-looking beast, known as Atopodentatus unicus, lived in the middle Triassic approximately 240 million years ago and is a brand new species and genus. Dr Xiao-chun Wu, a palaeontologist at the Canadian Museum of Nature in Ottawa, led the team that made the incredible discovery.  Their find in the Guanling Formation in Southwest China was published in Naturwissenschaften. Atopodentatus unicus belongs to the sauropterygians, a group of aquatic reptiles that developed from land ancestors and flourished during the Mesozoic before they became extinct at the end of the era.
