Physogaleus singularis (Probst, 1878)

Tooth type: Cutting-clutching.

The generic allocation of this species is debated. Based on illustrations from Voigt and Weber (2011) and Ebert et al. (2021), teeth of the extant species of the Carcharhinus sealei-dussumieri group (White 2012) are structured in a similar way to those of P. singularis . That group also contains the recent species C. coatesi (Whitley, 1939) and C. tjutjot (Bleeker, 1852) . They live in the shelf region, and their staple food is represented by bony fishes, followed by cephalopods (Cortés 1999; Ebert et al., 2021). According to its tooth shape, the lifestyle and diet of P. singularis was likely similar to those of the aforementioned recent species.
