The Prolagus species are fréquent in the Late Neogene vertebrate faunas of Europe (Lopez Martinez 1976. Weerd, 1979 Masini, 1989). Order: Rodentia Dowsich, 1821 Family: Sciuridae Gray, 1821 The morphological nomenclature and the measurements are after Cuenca Bescos (1988) Tribe: Petauristini De Bruijn et al, 1980 Genus: Pliopetaurista Kretzoi 1962 Pliopetaurista sp. (Fig. 13.) Material: 1 fragmentary m2 (?) no.inv.: 96.68. The metaconid is missing, but the intact part of the toothcrown fits the description and the figures by Sulimsky (1964). Mein (1970 and Black (1974). Tribe: Blackiini De Bruijn et al,. 1980 Genus: Blackia Mein, 1970 Material and measurements: no. inv. L W 1D4 95.69 1.09 1.15 Fig. 9. lp4 95.70 1.06 1.09 Figs. 10-11. Description D4 The shape of the occlusal surface is triangulär. It consists of 4 ridges, 4 conelets and 2 basins. The protoloph and metaloph are high, the posteroloph is low. The anteroloph is inclining: its highest point is the anteroconid. The enamel is wrinkled at the basins. The morphology of the toothcrown from Egyhazasdengeleg is similar to Fig. 8/1 of Daxner-Höck (1975) and Fig. 72. of Mein (1970). 174
