| Summary: | 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 |
