Sea's New King: Meet Tylosaurus rex, the 43-Foot Ocean Predator

Paleontologists reclassified twelve fossil specimens as Tylosaurus rex, a 43-foot, 3–4-ton marine reptile that ruled the ancient seas about 80–84 million years ago, distinct from the smaller Tylosaurus proriger by its serrated teeth and other features. The find, including the famous 'The Black Knight' skeleton now at Dallas's Perot Museum, comes from fossils in Texas and Kansas and could reshape how scientists understand early marine reptile evolution; the study was published May 21, 2026 in the Bulletin of the American Museum of Natural History.

Sea's T. rex: Scientists identify Tylosaurus rex as a giant mosasaur

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.

Sea's New King: Scientists Name Tylosaurus rex, the Ocean's Apex Predator

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.

New 43-Foot Mosasaur, Tylosaurus rex, Rewrites Sea Predator History

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.
