(Figs 86–89)

Referred material – 8teeth ( V.61.916, V.61.934, V.61.941, V.61.1279, V.63.482, V.63.483, V.69.883).

Description – A strong dignathic heterodonty is characteristic for the species. Upper teeth (Figs 86, 87) have triangular, labiolingually flattened crown with flat labial, and weakly convex lingual face. Th e cutting edges are serrated, they continue to the root lobes, forming serrated heels both mesially and distally. The root is mesiodistally wide, the lobes meet in an obtuse angle. Lower teeth (Figs 88, 89) have slender, upright cusp. The cutting edges and the heels are entire and smooth. The root is laterally expanded, the lobes are symmetrical with rounded extremities. The lingual protuberance bears a nutrient groove in all files.

Remarks – C. priscus is also widely reported from the Badenian of the Central Paratethys ( SZABÓ & KOCSIS 2016, table 2). This species has likely evolved from the Early Oligocene C. elongatus or the Late Oligocene C. gibbesi ( BOR et al. 2012, and references therein).
