Carcharhinus priscus (Agassiz, 1843)

Tooth type: Cutting-clutching.

A comparison of C. priscus teeth with the dentition of extant Carcharhinus spp. indicates a close morphological relationship with C. limbatus (Müller and Henle, 1841) , C. perezi (Poey, 1876) and C. brachyurus (Günther, 1870) (Reinecke et al., 2011; Bor et al., 2012; Andrianavalona et al., 2015; Collareta et al., 2021). That said, the teeth from those three extant species differ in one or more features from C. priscus (Bor et al. 2012) . According to this morphological affinity, it can be assumed that C. priscus had a similar diet and habits as the aforementioned extant species. Carcharhinus perezi lives inshore, from the surface to 65 m depth, while C. limbatus and C. brachyurus live in- and offshore, from the surface to a depth of 100 m (Voigt and Weber, 2011). All these species feature bony fishes in their diet (Voigt and Weber, 2011). Cortés (1999) also mentioned cephalopods as a second component of the diet of C. brachyurus and C. limbatus , establishing a TL of 4.2 for them. For C. perezi , in turn, a TL of 4.5 ±0.8 has been proposed (Froese and Pauly, 2019).
