Rhizoprionodon fischeuri (Joleaud, 1912)

Tooth type: Cutting-clutching.

The teeth of recent Rhizoprionodon spp. are very similar to the fossil representatives (Springer, 1964; Reinecke et al., 2011). Cortés (1999) mentioned bony fishes as staple food for the five extant species, assigning them TL values ranging from 3.8 to 4.2. Members of this genus live in the shelf region as well as offshore, down to depths of 500 m (Ebert et al., 2021).
