Description. Premaxilla: Premaxilla HLMD-Ez 1989 (Fig. 17 A-C) represents a small element, although with a more-or-less robust appearance. It is almost fully preserved. It is a single, unpaired T-shaped element (note, a groove or break is running through the midline, see remarks). The premaxilla bears seven-tooth positions with three teeth still attached to the dental parapet. The laterally extended maxillary processes are well developed. They are rather short than long. They possess an articulation facet for the maxilla on their dorsolateral surfaces. The fragmentarily preserved nasal process is wide, its external surface is flat. Here, a few small vestiges of osteoderms attached to the bone are present. In anterior and posterior views, the base of the nasal process is laterally constricted. Thus, the lateral margins in the lowest region of the process are rounded, having a cut-out like appearance. Dorsally, this region is wide, having more-or-less parallel lateral margins. The most dorsal preserved portion of the process narrows abruptly again, but the rest of the process - the posterodorsal portion with a termination - is broken off. On the internal side, there is a sagittal ridge running along the entire length of the preserved nasal process. It separates the facet for the nasals on both sides. On the lateral side, the ethmoidal foramen is located close to the base of the nasal process. The supradental shelf is formed by two segments, which are well expanded posteriorly. The dorsal side bears the vomerine process, which forms a small bulge. The short, weakly bilobed median incisive process is located ventral to the supradental shelf.
