2.1" Mosasaur Prognathodon Fossil Tooth Rooted In Matrix Cretaceous Dinosaur Era Crystal Quartz Fossilized partial carcasses bearing distinctive Fossilized partial carcasses bearing distinctive feeding marks provide compelling taphonomic evidence of predation and caching behavior—traces attributable exclusively to Archaeotherium within the White River fauna The 1908 discovery in Wyoming was particularly remarkable in that paleontologists actually recovered fossilized imprints of Edmontosaurus' skin but are especially well known from Europe and North America indicating that Prognathodon was not only a specialized hunter but also opportunistic in its feeding habits
