Figure 5.7 View FIGURE 5 -9
Referred material. right calcaneum ( GK 2-7; KZ-10), left calcaneum (BA-3), right cubonavicular ( GK 2-3), fragmentary astragalus (BA-2), distal extremity of metatarsal (KZ-8), and right p1? ( TP 641-9)
Description and Comparisons
In our sample, a cubonavicular and a calcaneum are about 50% larger than the largest astragali and cubonavicular referred to I. parvus ( Figure 5.7 and 5.9 View FIGURE 5 ). The cubonavicular has a large facet for the calcaneum as in Lophiomeryc chalaniati . The sustentaculum tali, although broken, is massive, and the anterior border of the calcaneal tali is slightly inclined as in L. chalaniati . A leaf-like tooth is identified as a p1 ( Figure 5.8 View FIGURE 5 ) and it is most similar to the p1 of L. chalaniati . Although limited, this material leads us to suspect the presence in the fauna of a large Lophiomeryx -like ruminant that would be slightly smaller in size than L chalaniati , a species known from the late Oligocene of Western Europe.

Referred material. right astragalus (KZ-9), fragmentary distal extremity of left tibia (BA-5)
Description and Comparisons
A unique and undamaged astragalus in our sample is much larger than the largest astragali referred to I. parvus . It is also larger than the lophiomerycid reported above ( Table 3). Moreover, unlike all the astragali of our present sample, it is the only specimen having the proximal and distal trochlea aligned, thus suggesting Pecoran affinities of this taxon ( Figure 5.10 View FIGURE 5 -11).
