Tylosaurus

Tylosaurus was a large marine reptile that lived during the late Cretaceous period, approximately 85-70 million years ago. It was a member of the mosasaur family, a group of reptiles that were well-adapted to life in the ocean. Tylosaurus was a carnivore, and it likely fed on a variety of prey, including fish, sea turtles, and other marine reptiles. Its body was long and slender, with a tail that was flattened and used for propulsion through the water. It had a small head with sharp teeth and a pair of large nostrils that it used to breathe while swimming. Tylosaurus is known from fossil remains found in North America and Europe. It was one of the largest and most formidable predatory reptiles of the late Cretaceous period.
