Сколько зубов было у Тиранозавра?
Tyrannosaurids, like their tyrannosauroid ancestors, were heterodont, with premaxillary teeth "D"-shaped in cross section and smaller than the rest. Unlike earlier tyrannosauroids and most other theropods, the maxillary and mandibular teeth of mature tyrannosaurids are not blade-like but extremely thickened and often circular in cross-section, with some species having reduced serrations. Tooth counts tend to be consistent within species, and larger species tend to have lower tooth counts than smaller ones. For example, "Alioramus" had 76 to 78 teeth in its jaws, while "Tyrannosaurus" had between 54 and 60.
