This illustration provided by Mark P. Witton in March 2023 depicts a juvenile Edmontosaurus being eaten by a Tyrannosaurus rex with a lipped mouth. The teeth on T. rex and other big theropods were likely covered by scaly lips, concludes a study published Thursday, March 30, 2023, in the journal Science. The dinosaur's teeth didn't stick out when its mouth was closed, and even in a wide open bite, you might just see the tips, the scientists found. – Photo: Mark P. Witton via AP
Sorry, Jurassic Park and toymakers everywhere.
Tyrannosaurus rex probably did not have those exposed jagged teeth.
