Abstract

A chondrichthyan assemblage is described from the Early Permian (Artinskian and Kungurian) of Mechetlino Quarry (Bashkortostan, South Urals). The assemblage includes the teeth of a symmoriiform, a sphenacanthid euselachian and an anachronistid neoselachian, as well as various denticles and scales. The dentition of Cobelodus aculeatus has been restudied. The teeth of a new genus of symmoriiform shark are described as Kungurodus, the internal structure of which is reconstructed using microtomography.
