MATERIAL A dozen isolated teeth, figured material includes FSAC Bouj-344 . DESCRIPTION AND REMARKS Some rare medium-sized shark teeth ( Fig. 4E, F ) with low or incipient cusplets correspond to a large unnamed Abdounia species previously observed in the middle to late Eocene of Egypt (included in C. frequens in Case & Cappetta 1990 : pl.7, fig. 147; Underwood et al. 2011 : fig. 2F). Occasional in MI, this unnamed species becomes common in GE A-C and younger series ( Underwood et al. 2011 ).
