A new species of massive marine reptile, Tylosaurus rex, has been described from fossils unearthed in northern Texas. The 43-foot-long mosasaur lived about 80 million years ago and ranks among the largest of its kind. Researchers published the findings on May 21, 2026.

The discovery was led by scientists at the American Museum of Natural History, the Perot Museum of Nature and Science in Dallas, and Southern Methodist University. Lead author Amelia Zietlow said the fossils had initially been misidentified as another species before detailed comparisons revealed distinct traits, including larger size and finely serrated teeth. The holotype specimen, found in 1979 near a reservoir outside Dallas, is now on display at the Perot Museum.

Lost fossils reveal diverse marine predators after Permian extinction

A cache of 250-million-year-old fossils rediscovered in Australia has shown a diverse community of early ocean predators following Earth's worst mass extinction. These marine amphibians, including species from the trematosaurid group, indicate a rapid global spread in the early Mesozoic era. The findings challenge previous views that limited such creatures to a single species in the southern hemisphere.

Study reveals tyrannosaurs scavenged their own kind

A 75-million-year-old fossilized foot bone from Montana shows bite marks from a smaller tyrannosaur feeding on a much larger relative. Researchers used 3D scans to document this evidence of scavenging behavior. The finding, published this year, highlights opportunistic feeding among these ancient predators.

Fossil jaws reveal giant ancient octopuses as apex predators

Researchers have uncovered evidence that octopuses from the Late Cretaceous period, around 100 million years ago, grew to lengths of nearly 20 meters and hunted as top predators. The findings, based on well-preserved fossil jaws from Japan and Vancouver Island, challenge previous views of early octopus evolution. Professor Yasuhiro Iba of Hokkaido University led the study, published in Science on April 23.
