PARADAKKAMYS ’ SEBOUI (JAEGER, 1977B)

Jaeger (1977b) erected this species on the basis of 18 upper molars and 12 lower molars from the early Late Miocene site of Oued Zra, middle-Atlas, Morocco. The holotype (OZ-20) is a left M2 housed at the SGM. It was originally placed in the genus Myocricetodon , but was later allocated to the genus Dakkamys by Lindsay (1988) and to Paradakkamys by Tong & Jaeger (1993). None of these allocations are confirmed by the cladistic analysis (see below).

The M1 of ‘ Paradakkamys ’ seboui differs from AJ 7 in having a well-developed longitudinal crest and an enterostyle that joins the posterior side of the protocone. The M2 of ‘ P. ’ seboui has the anterior arm of the hypocone connected to the posterior arm of the paracone, forming a new longitudinal crest, and a small enterostyle joined with the posterior arm of the protocone. In contrast, AJ11 and AJ12 lack a new longitudinal crest and show an isolated small enterostyle. The morphology of the m1 of ‘ P. ’ seboui is also very different from that of AJ 13 in lacking the strong reduction of the anterior part of the tooth and in having a well-developed longitudinal crest, which is lacking in the Arabian specimen.
