Tylosaurus was a type of mosasaur (mosasaurs were large, carnivorous, marine lizards). Tylosaurus existed about 83 million years ago. That was during the late Cretaceous time period of the Mesozoic era.
Tylosaurus was not a dinosaur. It was a type of mosasaur, which were large, carnivorous marine reptiles.
Mosasaurus hofmannii is probably the largest mosasaur, perhaps reaching a length of more than 17 meters (60 feet). Tylosaurus and Hainosaurus reached similar lengths but were less robust, probably only weighing half what Mosasaurus hofmanni of the same length weighed.
