Tylosaurus (TIE-low-SORE-us) was the largest member of the mosasaur family, a common reptile of the late Cretaceous. Although it lived its entire life in water, these immense creatures needed to surface constantly to breath air. An extremely powerful swimmer, the tylosaur had 4 paddle-like fins on its very long, stream-line body. It hunted fish, ammonites, even pteranodons and smaller mosasaurs! Similar to modern day snakes, the tylosaur’s lower jaw was jointed, allowing them to swallow oversize prey.
Out tylosaur skeleton is 45 feet long, with a 6 foot long head – the largest mosasaur ever found! The original was found in Wallace County, Kansas in 1911 by CD Bunker and is housed at the University of Kansas, Museum of Natural History.
