Artichnus giberti isp. nov., a possible holothurian burrow from the Miocene of El Camp de Tarragona Basin (NE Spain)

Abstract

A new ichnotaxon, Artichnus giberti isp. nov., is described in the marine Middle Miocene (Serravallian) of the El Camp the Tarragona Basin, north-eastern Spain. It is a mostly horizontal and rectilinear, tubular burrow with laminated lining. It is interpreted as the result of the burrowing activity of a deposit- or suspension feeding, worm-like animal, most likely a holothurian. This new Iberian occurrence enlarges both the known temporal and geographical records of the ichnogenus Artichnus, so far restricted to the Eocene of Poland.
