@article{10272/9106, year = {2002}, url = {http://hdl.handle.net/10272/9106}, abstract = {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}, publisher = {Sociedad Geológica de España}, keywords = {Bioerosion}, keywords = {Polychaete annelids}, keywords = {Upper Neogene}, keywords = {Iberian Peninsula}, title = {Estructuras bioerosivas de anélidos poliquetos (Serpulidae) en el Neógeno superior del Sur de la Península Ibérica}, title = {Bioerosive structures of polychaete annelids (Serpulidae) from the Upper Neogene of the South Iberian Peninsula}, author = {Santos, Ana Alexandra Guerreiro dos and Mayoral Alfaro, Eduardo and Muñiz Guinea, Fernando and Vera Peláez, José L. and Lozano Francisco, María C.}, }
