Spermophilus primigenius (Kormos, 1934)

( Figs 11–12 )

Material – Isolated teeth: 1 right M 2; 1 right M 3; 1 left M 3; 2 left P 4; 1 left M 2; 2 right M 2.

Description – The premolar is relatively small, front is narrower than rear (like Sciurus ) and consisting of four cusps. On the labial side it is protoconid and hypoconid, on the lingual side is metaconid and entoconid. The anterior incisal tip is the longest. Between this and the protoconid a slight trace of the anterior inner cusp (paraconid) can be seen. A tiny accessory cusp is observed between metaconid and entoconid. The molars are large and broad, M 1 and M 2 are rhombic and consisting of the above-mentioned four main elements. The paraconid is weakly indicated on both teeth, between the meta- and entoconid, on the other hand, there are two clearly perceptible intermediate cusps. On the last molar (M 3), only one can be observed, but it is more developed. The premolar has two roots in all cases, whereas the molars have four roots.
