Material. Three incisors (QHJ-12–14); 1 right M 3 (QHJ-22); 1 left M 3 (?) (QHJ-42); 1 condyle part of left mandible (QHJ-47); 1 proximal part of humerus (QHJ-46).
Description. The referred incisors are long, triangular, with smooth crowns, with deep hollows in their occlusal surfaces. The last character suggests that the animal was juvenile. The ring of central enamel is narrow and nearer to the lingual border. Two of these teeth belong to the lateral side, because of the elliptical-shaped occlusal surfaces. The other one likely represents a medial tooth because it displays a circular occlusal surface ( Figure 4.3 View FIGURE 4 -5).
A well-preserved right M 3 displays a high crown. In occlusal view, the protocone is long and rounded, metacone is deeper and smaller than the paracone, and the parastyle is triangular ( Figure 4.6 View FIGURE 4 -7). Another molar, presumably a left M 3, is much more worn and most of the cusp and crenulation patterns are lost ( Figure 4.8 View FIGURE 4 -9). The rest of material is tentatively referred to Equus .
Remark. We consider a caballoid horse is represented, because of the long and rounded protocone preserved on a M 3 and the dimensions of these molars ( Arceredillo, 2008).
