( FIG. 2I–O View Figure 2 )
Referred specimens —SC96.97.42, second upper right anterior tooth ( Fig. 2N View Figure 2 ); SC96.97.43, lower left lateral tooth ( Fig. 2O View Figure 2 ); SC96.97.44.1, second lower right anterior tooth ( Fig. 2M View Figure 2 ); SC96.97.44.2, four teeth; SC96.97.45, 236 incomplete teeth; SC2001.1.55, third lower right anterior tooth ( Fig. 2I View Figure 2 ); SC2001.1.56, anterior tooth; SC2001.1.57, third upper right anterior tooth ( Fig. 2J, K View Figure 2 ); SC2001.1.58, six incomplete anterior teeth; SC2001.1.59, first lower right anterior tooth ( Fig. 2L View Figure 2 ); SC2001.1.60, three posterior teeth; SC2001.1.61, 40 incomplete teeth; SC2013.38.8, anterolateral tooth; SC2013.38.9, four partial teeth; SC2013.38.10, three partial teeth; SC2013.38.11, lateral tooth; SC2013.38.12, 14 tooth fragments; SC2013.38.13, tooth; SC2013.38.14, two incomplete anterior teeth.
Remarks —The 332 teeth in the sample are similar to extant Carcharias taurus Rafinesque, 1810 , and examination of two Recent dentitions of this species (SC2001.120.6 and SC86.62.2) allowed us to identify various anterior and lateral positions in the fossil species. Unfortunately, diagenetic alteration of the teeth makes confidently assigning the fossil material to any of various species that have been reported from Eocene strata difficult, as characteristics that have been used for species identification, like the number and shape of lateral cusplets and crown ornamentation, are generally not evident or imperfectly preserved.
