Nanotyrannus, meaning "dwarf tyrant," is a contentious genus within the tyrannosaurid family, likely representing a juvenile form of Tyrannosaurus. Known primarily from a small skull, it lived approximately between 72.1 and 66 million years ago. The distinguishing characteristic of adult Tyrannosaurus rex lies in its dentition: Nanotyrannus possessed 14 to 15 teeth per side in the maxilla and 16 per side in the lower jaw, exceeding T. rex’s 11–12 and 11–14 tooth positions, respectively. Additionally, the presence of fused bones further differentiates it. Fossil evidence suggests these theropods hunted cooperatively, preying on large Late Cretaceous herbivores such as ceratopsians and hadrosaurs.
