Persichnus igen. nov. and Associated Ichnofossils From the Upper Cretaceous to Eocene Deep-Sea Deposits of the Sanandaj Area, West Iran

Persichnus igen. nov. is a replacement name for Acanthus Grossheim 1946. The type and only known ichnospecies of Persichnus is P. dodecimanus (Grossheim, 1946) (new combination), which occurs among trace fossils of the Nereites ichnofacies in the Upper Cretaceous to Paleogene deposits of west Iran. The new ichnogenus is interpreted as a graphoglyptid burrow. Associated trace fossils include Cosmorhaphe lobata, Paleodictyon majus, cf. Planolites beverleyensis, Scolicia strozzii, Scolicia isp., Spirophycus bicornis, Squamodictyon isp. and Treptichnus isp.
