Scientists discover giant sea predator Tylosaurus rex that terrorized ancient oceans
Scientists have discovered a new species of giant sea predator named Tylosaurus rex, which lived 80 million years ago. This colossal mosasaur, measuring up to 43 feet long, is believed to have been one of the most fearsome predators in ancient oceans. The discovery challenges previous understandings of mosasaur evolution and highlights the violent nature of this species.
- ▪Tylosaurus rex was identified from fossils found in Texas and measures up to 43 feet long.
- ▪The species had adaptations for powerful jaw and neck muscles, making it a formidable hunter.
- ▪Evidence suggests that Tylosaurus rex exhibited violent behavior, with injuries likely caused by other members of the same species.
