Description
TABLE 1. — Denticle length measurements for the 44 teeth attributed to Abelisauridae indet. found at the Massecaps locality.Total crown length is also reported (when possible) for each tooth. n.a., means not applicable. For comparison, the width of the seven consecutive grooves visible on the mark worn by tooth M5246 was measured. Specimens housed in the Muséum of Cruzy by the Association culturelle archéologique et paléontologique.
