Description
Nothogomphodon was unusual among therocephalians for its sectorial dentition, a feature it shared with cynodonts and which would have allowed it to shear meat more effectively.{{cite journal |author1 = Liu Jun|author2 = Abdala, Fernando|year=2015|title= New discoveries from the Sinokannemeyeria-Shansisuchus Assemblage Zone: 2.
