Zramys cf. salemi Jaeger, 1977

Fig. 4 F View Figure 4

Material and measurements.

One fragment of right M 1-2 ( IPS-PAM 207-07 ) (W: 1.30); one right m 3 (L: ca. 1.99; W: 1.44) ( IPS-PAM 207-10 ).

Description.

m 3 (Fig. 4 F View Figure 4 ). The anterior wall of the tooth is absent, but a very low, residual labial anterolophid can still be recognized at the base of the protoconid. A deep mesosinusid is directed forward. A transverse, deep sinusid is also present. The hypoconid and entoconid are fused, forming a round cusp, with no evidence of a posterosinusid.

Remarks.

Although in the preliminary classification by Tesón et al. (2010) the m 3 of Zramys from PAM 207 was assigned to Zramys cf. hammamai , this tooth is larger than that species, as well as larger than the m 3 of Zramys gueltae , Zramys dubius , Zramys semmnensis , Zramys jaegeri , and Zramys cavatus (see Jaeger et al. 1973; Jaeger 1977; Robinson et al. 1982; Ameur 1984; Coiffait-Martin 1991). In size, it matches the m 3 of Zramys haichai from Oued Zra ( Morocco) and Zramys salemi from the type locality of Sidi Salem ( Algeria; Jaeger et al. 1973). However, the m 3 from PAM 207 exhibits a more simplified pattern than the m 3 of Z. haichai from Oued Zra, with the hypoconid-entoconid pair reduced to a single round cusp, not delimiting a ring as in the type population of Oued Zra ( Jaeger 1977, pl. 4, fig. 7). Therefore, we refer this material to Zramys cf. salemi . In addition to the m 3, a fragment of M 1-2 retains the labial wall of the paracone and the hypocone. The posterior ectoloph of the paracone does not reach the anterior wall of the hypocone.
