(Figs 81–85)

Referred material – 8 teeth ( V.61.924, V.61.1281, V.69.1066, V.69.1089, V.69.1096).

Description – Both faces of the crown are smooth, the labial one is flat, while the lingual is convex. The convex mesial cutting edge bears slightly irregular serrations varying between fine and uniform. The straight to weakly convex distal cutting edge is shorter than the mesial edge, and finely serrated. A distal crown heel is present, which is separated from the distal cutting edge by a deep notch. The heel is convex in labial (and lingual) view, it declines to the distal crown margin. The root is apicobasally low and mesiodistally wide, the root lobes meet in an obtuse angle forming a weak lingual protuberance.

Remarks – This extinct tiger shark species is widely reported from the Badenian of the Central Paratethys ( SZABÓ & KOCSIS 2016, table 2).
