Paleontologists have identified Tylosaurus rex as a distinct, giant mosasaur—about 13 meters long with serrated teeth and powerful jaws—living roughly 80 million years ago in the Western Interior Seaway; it was the sea’s equivalent of Tyrannosaurus rex in size and ferocity.
Scientists have described Tylosaurus rex, a new mosasaur species that inhabited North America’s inland seas about 80 million years ago. Reaching up to 43 feet in length, it was larger than its close relative Tylosaurus proriger and likely the ocean’s apex predator, with a robust jaw and a scimitar-shaped skull. The species was identified after reclassifying fossils held in more than a dozen museums, including a nearly complete holotype at the Perot Museum in Dallas. The discovery reveals greater mosasaur diversity and shows that sea predators crowned the Cretaceous seas as fearsome as the land-dwelling T. rex was on land.
Paleontologists describe a gigantic new mosasaur, Tylosaurus rex, up to 43 feet long with serrated teeth, discovered mainly in Texas. Larger than the previously known Tylosaurus proriger, it indicates a formidable open-water predator in North America’s Western Interior Seaway, with several famous museum specimens reclassified under the new species and findings published in the Bulletin of the American Museum of Natural History.
