Lacertidae indet. ( Fig. 12B View FIG , B’)
MATERIAL EXAMINED. — Six dentaries ( ISER Tt-0450/- 1-6).
DESCRIPTION
All the available dentaries belonged to relatively small individuals. The bone is slender with the meckelian groove opened throughout the dentary length and moderately enlarged posteriorly. The horizontal lamina is relatively thin and it tapers posteriorly; the subdental shelf is of moderate width. The labial surface is smooth and slightly convex. In ISER Tt-0450/1 a number of six foramina pro rami nervorum alveolarium inferiorum are preserved. From the level of the posteriormost foramen the imprint for the attachment of the coronoid is observed. The anterior teeth are unicuspid, while the remaining ones are distinctly bicuspid. The shape of the tooth shaft is more or less cylindrical and more than one third of the tooth height projects above the dental parapet.
REMARKS
The size and morphology of the above dentaries approaches those seen in smaller lacertids, including the extinct genera Miolacerta Roček, 1984 , known from the late early Miocene (MN 4) of Dolnice, Czech Republic ( Roček 1984) and Edlartetia Augé & Rage, 2000 , described from the middle Miocene (MN 6) of Sansan, France ( Augé & Rage 2000). However, the dentary in Miolacerta is devoid of imprint for the coronoid attachment, and typically bears tricuspid teeth, while in Edlartetia the teeth are
narrowed below the apex ( Rage & Bailon 2005).
