Ichnogenus Pinaceocladichnus Mayoral, 1988

Type ichnospecies: Pinaceocladichnus onubensis Mayoral, 1988 , Arenas de Huelva Formetion ( lower Pliocene ), Moguer, Huelva Province, Spain .

Diagnosis. —Boring pattern constituted by a regular network of fine tunnels, slightly curved and laterally opposite (cited from Botquelen and Mayoral 2005).

Remarks. —This boring is a network of stolon tunnels with apertures produced by ctenostome bryozoans similar to those produced by the genus Immergentia Silén, 1946 , or Terebripora d’Orbigny, 1847 ( Mayoral 1988). This trace fossil occurs in marine environments from the littoral to neritic zones on calcareous substrates. Pinaceocladichnus occurs since the Ordovician ( Mayoral 1991; Toom et al. 2019).
