Abstract
This report identifies several cases of similar-appearing multiple lesions in the mandibles of both humans and the dinosaur Tyrannosaurus rex (T. rex). A diagnosis and potential etiologies are discussed. The appearance of these lesions in prehistoric fossils suggests that this pathology is an ancient affliction which predates humans and our mammalian ancestors. Lytic lesions of the oral structures have occurred in man and higher animals throughout time. The causes range from congenital anomalies, trauma, and infections to benign and metastatic neoplasms. Not only mammals suffer from these conditions; reptiles and birds experience similar diseases.
