About Tylosaurus Rex

  • Tylosaurus rex belongs to the mosasaur family, which is a group of marine reptiles from the time of dinosaurs.
  • It was not actually a dinosaur, but rather a sea creature linked to land lizards.
  • Modern monitor lizards are among its closest living relatives today.

Period and Habitat

  • This creature lived approximately 80 million years ago during the Cretaceous Period.
  • A huge inland sea known as the Western Interior Seaway split North America into two distinct landmasses during that era.

Size and Physical Features

  • The biggest known specimen is named Bunker and measures about 13.2 metres in length.
  • This makes it larger than the famous Tyrannosaurus rex specimen Sue, which reaches about 12.2 metres in length.
  • Tylosaurus rex featured a sleek body, a long snout, powerful teeth with fine edges for slicing meat, four flippers shaped like paddles, and a strong tail.

Predatory Traits and Classification

  • Its strong jaw and neck muscles show that it could overpower large prey and act as an apex marine predator.
  • Mosasaurs were sea reptiles found all over the world that developed from land-living lizards and grew into top hunters near the end of the dinosaur era.
  • The name Tylosaurus rex translates to king of the tylosaurs, inspired by Tyrannosaurus rex, even though the two did not live at the same time.
