MATERIAL EXAMINED. — Six incomplete maxillae (
SPV
723), five incomplete dentaries (
SPV
724), four fragments bearing teeth (
SPV
725).
DESCRIPTION
Ŋe teeth are all pleurodont; the anterior ones have a single cuspid, others (probably from the midsection of the tooth row) are bicuspid, whereas the larger teeth, i.e. from the posterior section, have three cuspids. Well-marked vertical striae occur on the apices. None of the teeth is amblyodont (i.e. “molariform”). On the maxillae, the anteriormost teeth are acute and recurved.
DISCUSSION
Ŋe combination of mono-, bi- and tricuspid teeth in a single tooth row, presence of anterior recurved maxillary teeth and the striation of apices point to
Lacerta
s.l.
filholi
. Ŋis small lizard is frequent in the Oligocene of western Europe. However, the preserved parts of the maxillae do not bear osteoderms. Ŋerefore, although this absence may be only of ontogenetic nature, assignment to this species cannot be accepted without reservation.
