Lampanyctus sp.

Figure 12f

Material 2 specimens, SMF PO 101.196 , Dar bel Hamri, Zanclean .

Discussion Small and high-bodied otoliths that resemble Lampanyctus latesulcatus Nolf & Steurbaut, 1983 , from the Tortonian of Italy. Te specimens from Dar bel Hamri differ slightly in the caudal pseudocolliculum extending beyond the entire cauda, while it is posteriorly reduced in L. latesulcatus . Tey may thus represent a different species. Van Hinsbergh and Hoedemakers (2022) identified the extant L. crocodilus and L. photonotus from the Piacenzian and the latter also from the Zanclean of Estepona near Málaga, Spain.
