One type of clement with strong, symmetrical or asymmetrical, lateral costae; other type with more or less twisted, carinate or grooved cusp; basal cavity of moderate size, restricted to base. [Absence of geniculate elements in the apparatus distinguishes Protopanderodus from Drepanoistodus, Paltodus, and Paroistodus. Apparatus reconstruction: LINDSTRO, 1971.]
