Dinosaurs don’t need a dentist

Berlin’s crowd-puller T. rex Tristan Otto is a unique research object: Using the skull bones of Tyrannosaurus rex, scientists from the Museum of Natural History have succeeded in finding new evidence that the teeth of the giant predatory dinosaur have been changed regularly. The teeth of Tyrannosaurus rex were constantly replaced by new ones. This has now been published in the scientific magazine Historical Biology.
