The Earliest Case of Neoplastic Bone Lesion in Tetrapods
The results of the examination of a bone neoplastic lesion in lower jaw of Early Triassic temnospondyl amphibian Benthosuchus korobkovi from Tikhvinskoye locality (Yaroslavl region, Rybinsk district; Early Olenekian) are presented. Multispiral computer tomography confirmed with a sufficient degree of confidence the neoplastic nature of the lesion; the most probable diagnosis: non-odontogenic osteoma. Hemangioma and bone fibrous dysplasia are also possible.
