Lacertidae sp. indet. 2.

Figure 6 E-F

Material. UBB V 959/1-4 one fragmentary frontal, one fragmentary postorbital, two fragmentary dentaries.

Description. Both the frontal (a posterior fragment) and the postorbital (proximal part) are extremely fragmentary and covered with an outer sculpture. The dentaries preserve small portions from the middle portion (UBB V 959/3) and posterior portion (UBB V 959/4) of small-sized lacertid specimens ( Figure 6 E-F). The horizontal lamina is thin and the subdental shelf is shallow. The tooth shaft is cylindrical and moderately high projecting nearly half of their height above the dental parapet. The anterior tooth crowns apparently were monocuspid, those from the middle section bicupsid, whereas the posterior ones are tricupsid.

Remarks. The specimens differ from those of Lacertidae sp. indet. 1., by their smaller size and by the morphology of tooth crown in the posterior teeth displaying the tricuspid condition.
