Abstract :
Michin csernai gen. et sp. nov. from the Early Cretaceous (Albian) limestones of the Tlayْa Quarry, Puebla State, Central Mexico, is assigned to the Teleost clade Pachyrhizodontoidei as it possesses the enlarged inner premaxillary tooth, which is a unique synapomorphy of this clade. Additionally, the occurrence of relatively primitive characters (e.g., united parietals, angular and articular completely fused, caudal fin with five uroneurals) suggests that Michin csernai represents the most basal representative of the pachyrhizodontids.
