Churcher, Charles S., Iuliis, Gerardo De & Kleindienst, Maxine R., 2006, A new genus for the Dipnoan species Ceratodus tuberculatus Tabaste, 1963, Geodiversitas 28 (4), pp. 635-647 : 637

Genus Retodus n. gen.

TYPE SPECIES. — Ceratodus tuberculatus Tabaste, 1963 .

ETYMOLOGY. — From the Latin, rete, net; - odus, Latinised Greek -Óδούυς, toothlike, referring to a network of ridges on the occlusal surface of a tooth plate.

DIAGNOSIS. — The same as Retodus tuberculatus n. comb.

REMARKS

The new lungfish tooth plate (ROM 47638) reported here preserves features unknown in the species previously known as Ceratodus tuberculatus and indicates that the species cannot be referred to an already described genus. Although insufficient material of the species is known to permit a phylogenetic analysis, it is apparent that it forms a distinct clade, and thus merits generic distinction as Retodus n. gen.
