There’s a new T. rex in the fossil record, only this one terrorized the ancient seas. New research led by
scientists at the American Museum of Natural History, the Perot Museum of Nature and Science, and
Southern Methodist University uncovers a new, massive species of mosasaur, a marine reptile that lived
during the age of the dinosaurs. One of the largest mosasaurs known to date—stretching up to 43 feet
long—this top predator was described from 80-million-year-old fossils that were found primarily in
northern Texas decades ago. It was named Tylosaurus rex, or T. rex for short, meaning “king of the
tylosaurs.”
