Genus Cassisodus nov.
Type species: Cassisodus margaritae sp. nov.
Derivation of the name: Latin cassis = helmet; Greek ‘odous = tooth.
Diagnosis.—Teeth with euselachian bases and crowns composed of a prominent median cusp and two to four lateral cusps on each side. All the cusps smooth, rounded in cross section, slightly compressed mesio−distally, provided with at least one accessory cusplet on both lingual and labial sides. The lateral rami of the crown gradually narrowing and lowering outwards, and gently curved linguad.
The overall appearance of the teeth and especially the labial overhang of the main cusp, with its accessory cusplet, resemble Lissodus Brough, 1935 . However, the occurrence of accessory cusplets on both sides of lateral cusps is unique of Cassisodus .
