ABSTRACT

A new ichnotaxon, Artichnus giberti isp. nov., is described in the marine middle Miocene (Serravallian) of the El Camp de Tarragona Basin, north eastern Spain. It is a mostly horizontal and rectilinear, tubular burrow with laminated lining. Artichnus giberti 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 extends the known temporal and geographical records of the ichnogenus Artichnus, which was previously restricted to the Eocene of Poland.
