The Tyrannosaurus rex and its relatives had the dinosaur equivalent of lips, according to a new study. The latest findings dispute classic depictions of the snarling predators.
Palaeontologists have given one of the most famous dinosaurs a makeover, proposing that the Tyrannosaurus or the T-rex did not sport ferocious, protruding chompers but rather proportionally sized.
A new study suggests that predatory dinosaurs, such as Tyrannosaurus rex, did not have permanently exposed teeth as depicted in films such as Jurassic Park, but instead had scaly, lizard-like lips covering and sealing their mouths.
