Abstract
Four species ofOphisaurus,O.fejfari,O. spinari,O. robustus andO. holeci, are recognized on the basis of parietals from the Early Miocene of the Czech Republic and Germany. The fifth species,O. acuminatus, is described from the Late Miocene of Germany, but its parietal is not preserved. This paper describes newO.fejfari,O. spinari,O. robustus andO. holeci specimens from the Early and Middle Miocene of the Czech Republic and Germany. TheO. fejfari andO. holeci parietals from Germany are the first records of these species outside the Czech Republic. This paper provides a significant contribution to the understanding of both interspecific and intraspecificOphisaurus variability in the Cenozoic of Europe. A well-preserved parietal ofAnguis rarus sp. nov. is described from the Early Miocene of Germany. This is the first record of the parietal ofAnguis in the Cenozoic. A new parietal from the Middle Miocene of Germany is described asPseudopus sp. It differs from the contemporaneousP. laurillardi only in the absence of the large and distinctly laterally projecting anterolateral processes of the parietal. In the Miocene,Ophisaurus andPseudopus exhibit a higher diversity than that of the preceding geological periods of the Cenozoic. Besides,Ophisaurus emigrates from Europe to (1) Asia and via the Bering Strait to North America, and (2) North Africa during the Oligocene and Miocene. By contrast,Anguis andPseudopus are limited to Eurasia. The palaeobiogeography of members of Anguinae is discussed.
