Steneosaurus bollensis Jurassic Posidonia Shale Formation, Holzmaden, Germany A rare find, this magnificently articulated ten-foot-long Steneosaurus bollensis once terrorized the Jurassic seas. The specimen was discovered in the world famous Posidonienschiefer Shale, a lithostratographic formation; shale from this geologic formation has actually been used as building material in Germany for centuries. The preparation of specimens from this locality is supremely arduous, as the density of the stone matrix is similar to that of the fossils. As evidenced by the present superlative specimen, the skull of Steneosaurus was very light and narrow compared to that of modern crocodiles, with large openings and a long, narrow snout. The nostrils were at the tip of the snout and connected to the throat by a long bony tube. Evidencing its carnivorous habit, it possessed countless sharp teeth, which were probably used to eat fish. Teeming with marine life during the Jurassic Period, 200 to 146 million years ago, in the area now known as Germany, the warm shallow seas supported abundant marine life, including apex predators such as ichthyosaurs, plesiosaurs and the primitive crocodile, Steneosaurus bollensis.
