A new decapod burrow system from the NW Mediterranean Pliocene

Abstract

A new ichnofossil, Sinusichnus sinuosus ichnogen. nov. ichnosp. nov, is described from the marine Pliocene of the northwestern Mediterranean. It is a branching burrow system comprising horizontal and regularly sinuous elements. It is interpreted as the feeding, dwelling burrow of a deposit-feeder crustacean. The new trace fossil is very similar in both configuration and function to the well-known ichnogenus Thalassinoides.
