Description
Replica of the sea reptile Prognathodon, a genus of mosasaur that prowled the oceans between 66 and 84 million years ago. Prognathodon was a wide ranging genus, with the remains of various species being found from ancient sea beds of North America, Africa, the Middle East, Europe, and New Zealand. This particular skeleton is based on a remarkably well preserved skeleton of the species P. kianda. Found in Angola, the specimen is thought to be around 72 million years old and represents an individual that had grown 7m (23ft) in length before it died. Among its remains were also the remains of three mosasaur heads in its gut, which gives scientists an window into what it ate - including cannibalism, as one skull belongs to a member of its species. This particular skeleton is the centerpiece of a new exhibit at the Smithsonian National Museum of Natural History, Sea Monsters Unearthed , featuring several mosasaur fossils (as well as a couple of other sea reptiles) discovered in Angola and will run until 2020.
