👉 Acidodontium is a genus of extinct dinosaur that lived during the Late Cretaceous period, which was around 65-74 million years ago. It was characterized by its large jaws and teeth made of calcium carbonate, which allowed it to have a very powerful bite force. This species likely had a diet rich in meat-eating dinosaurs, including the Tyrannosaurus rex, although their exact role within this group is not clear.
