Luciobarbus sp.

Material.

Two pharyngeal teeth ( IPS-PAM 207-15 , IPS-PAM 207-16 ).

Description and remarks.

Both pharyngeal teeth are elongate and twisted along their longitudinal axis. The tooth crown shows an anteriorly directed pointed hook.

The genus Luciobarbus (barbel) has pharyngeal teeth arranged in three rows, with the following formula: five teeth in the first row, three in the second, and two in the third. Similar to other Barbini genera, the teeth in the first row are larger than those in the other two rows. The two small pharyngeal teeth found belong to the third row. In both cases the tooth body is compressed at the foot-crown border, and the crown is slightly narrower than the base. The pharyngeal teeth are also characterized by the presence of a hook at the top of the grinding surface ( Escala and Miranda 2002; Vasylan et al. 2019).

Several species belonging to the genus Luciobarbus are currently present in Morocco ( L. callensis , L. guercifensis , L. lanigarensis , L. maghrebensis , L. magniatlantis , L. nasus , L. pallaryi , L. rabatensis , L. yahyaouii , and L. zayanensis ) ( Clavero et al. 2017). Due to the lack of a complete pharyngeal arch, classification at the species level is not possible for these remains.
