Estructuras bioerosivas de anélidos poliquetos (Serpulidae) en el Neógeno superior del Sur de la Península Ibérica

New superficial etching traces corresponding to annelids of the family Serpulidae are described. These traces present an elongated, sinuous and/or spiralated pathway in a plan view. They consist in a very shallow central channel flanked by a lateral zone that can exhibit either faint, spread, obliqu...

Descripción
Sumario:New superficial etching traces corresponding to annelids of the family Serpulidae are described. These traces present an elongated, sinuous and/or spiralated pathway in a plan view. They consist in a very shallow central channel flanked by a lateral zone that can exhibit either faint, spread, oblique grooves or perpendicular, dense lines. The external part of this zone shows normally, a very narrow margin. The flanks of the traces are nearly parallel in the proximal part and clearly divergent in the opposite end
