Original diagnose after Ameghino (1901) p. 83 [50]: Carcharodon chubutensis n. sp. Aussi grande que C. megalodon ; les dents en différent par le bord postérieur plus creusé, et par la présence sur la base d'une paire de saillies larges et basses et á bords dentelés comme le grand cône principal; ces saillies sont accompagnées d'une paire de tous petits tubercules basales. Ces caractères sont plus fortement marqués sur les dents postérieures que sur les antérieures.
