Tylosaurus

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Tylosaurus (Greek /tylos "protuberance, knob" + Greek /sauros "lizard") was a mosasaur, a large, predatory marine lizard closely related to modern monitor lizards and to snakes. Along with plesiosaurs, sharks, fish, and other genera of mosasaurs, it was a dominant predator of the Western Interior Seaway during the Late Cretaceous. Tylosaurus proriger was among the largest of all the mosasaurs (along with Hainosaurus and Mosasaurus hoffmannii), reaching maximum lengths of 15 meters or more (49+ ft).
