An intriguing new diapsid reptile with evidence of mandibulo-dental pathology from the early Permian of Oklahoma revealed by neutron tomography

The tooth bearing elements of the lower jaw showing the strongly recurved predatory dentition of Maiothisavros. On the right lower jaw the pathology is shown, with teeth missing from the middle and bone having closed the tooth sockets.

This animation highlights the skeletal and dental anatomy of Maiothisavros, including the pathology, for better visualization of this unique fossil. The new diapsid reptile was studied using neutron computed tomography (ANSTO, Australia), revealing extensive internal data that were otherwise hidden by the encasing rock. Mechanical or chemical preparation of the fossil was impossible for study of the internal structures because of the small size and delicate condition of this unique specimen.
