MATERIAL EXAMINED. — One parietal ( ISER Tt-0440), two frontals ( ISER Tt-0441/1 and 2), seven maxillae ( ISER Tt-0442/1-7), four dentaries ( ISER Tt-0443/-

1-4).

DESCRIPTION

Parietal

ISER Tt-0440 preserves the posterior portion of parietal only.The dorsal surface is sculptured as small pits, while in ventral view there is a relatively long facies trapezoideus bordered by the medial laminae of the exoccipital processes.

Frontal

The sculpture on the dorsal surface is formed by small pits and low ridges which trend anteroposteriorly; near the lateral margin the ridges run laterally or anterolaterally ( Fig. 12C, D View FIG ).

Maxilla

ISER Tt-0442/1 preserves the anterior part of a maxillary fragment with the crista dentalis and lower part of vertical wall of maxilla ( Fig. 12E View FIG , E’). In lateral view, two superior alveolar foramina and two additional openings are present and there is an extremely small surface displaying a labial sculpture; five tooth positions are preserved. The teeth are pleurodont and the tooth crowns have bicuspid tips. The main cusps are positioned distally while the mesial cusps are of much smaller size. The striations of the tooth crown are restricted to the lingual side of the main cusps.

Dentary

The meckelian groove is widely open throughout the dentary length. The symphysis in ISER Tt-0443/1 extends to the fourth mandibular length. The dentition, except the first three mandibular teeth, is with bicuspid tips. The subdental shelf in the first mandibular portion is reduced (up to the level of the 12th-13th tooth position) with the lingual surface of the horizontal lamina flattened ( Fig. 12F View FIG , F’). From the level of the 13th-14th tooth position the subdental shelf widens moderately and the horizontal lamina displays a convex lingual margin. In lateral view, the labial surface of the fragmentary dentaries is strongly convex and smooth, displaying a row of three or four foramina pro rami nervorum alveolarium inferiorum. An elongated and only partially preserved shallow groove, situated parallel to the posterior part of the dental parapet, marks the attachment with the

coronoid. The tooth shaft is more or less cylindrical

and projecting about one third above the tooth parapet. The tooth crown is bicuspid with morphology similar to that observed in maxillae.

REMARKS

The available specimens belonged to large sized individuals comparable to L. viridis (Laurenti, 1768) - L.trilineata Bedriaga, 1886 . Unfortunately these remains are unsuitable for a more precise assignment.
