DESCRIPTION The African Galeocerdo eaglesomei is unfrequent compared to the contemporaneous and worldwide species G. latidens Agassiz, 1843 . However, G. eaglesomei differs from it by teeth with a higher crown, a longer and abrupt distal heel without distinct notch with main cusp, with more numerous and larger denticles and with a deeper basal medial concavity of the root deeper. Our teeth ( Fig. 3 G-I), as those from the Lower Priabonian of SA, southwestern Morocco ( Adnet et al. 2010 ), are relatively larger and display a much higher crown compared to the Lutetian specimens, which makes it possible to provisionally assign these to G. eaglesomei , to which the youngest specimens from Southwestern Morocco are likely affiliated. REMARKS Relatively scarce teeth of Galeocerdo cf. eaglesomei are quite similar in shape to G. eaglesomei from the late Lutetian of Nigeria ( Andrews 1920 ), the Lutetian-Bartonian of GA ( Strougo et al. 2007 ), the middle to late Eocene of Madagascar ( Samonds et al. 2019 ) and to those recovered in MI, Egypt , where it is one of the most conspicuous elements of the uppermost Lutetian-lowermost Bartonian assemblage ( Underwood et al. 2011 ).
