Fig. 11. Comparison of talonid morphology, in lingual view of two Egyptian afrosoricid placentals. A. Dilambdogale gheerbranti (DPC 24103A), from the earliest late Eocene (earliest Priabonian; ~37 Ma) locality BQ−2, Birket Qarun Formation, Fayum Depression, northern Egypt. B. Qatranilestes oligocaenus (YPM 24203), from the late early Oligocene (late Rupelian; ~30 Ma) Quarry I, upper sequence of the Jebel Qatrani Formation, northern Egypt. Specimens are scaled to the same approximate m2–3 length to facilitate comparison. Note the much larger hypoconid and relatively capacious and concave talonid basin in Dilambdogale. Also note that the m2 entoconid is broken in DPC 24103A, but is relatively well−developed in other specimens.
