Hemipristis serra Agassiz, 1835

( Figs 79, 80 )

Referred material – 3 teeth ( V.61.937, V.62.405, V.63.480).

Description – Specimens V.61.937 and V.62.405 are embedded in a piece of limestone matrix in labial aspect ( Figs 79, 80 ). All of the here referred teeth have similar morphology. The crown is triangular, and distally inclined. Both cutting edges are coarsely serrated. The root is bilobate, the lobes are well-separated, with angled extremities. This morphology refers the teeth as upper files.

Remarks – The species is also widely reported from the Badenian deposits of the Central Paratethys ( SZABÓ & KOCSIS 2016, table 2). The genus is represented by a single extant species H. elongata , distributed in the Indo-West Pacific ( EBERT et al. 2013).
