Genus PANDERODUS Ethington, 1959

Type species. Paltodus unicostatus Branson and Mehl, 1933 .

Diagnosis. Apparatus consists of one unpaired (aequaliform) and five paired (tortiform, falciform, graciliform, truncatiform, arcuatiform) coniform element morphologies. The graciliform elements can be further subdivided in most species. Deep furrows extending most of the length of the elements, expanded basal cavities, and round to slightly laterally compressed basal cavities are characteristic of Panderodus . In most reconstructions of panderodontid apparatuses, different element types can be distinguished by the degree of curvature and asymmetry of the elements, the amount of torsion of the cusps, lateral compression of elements, and ornamentation by costae. See Sansom et al. (1994) for thorough description of the Panderodus apparatus, and Sansom and Smith (2005) for diagnosis of genus.
