摘要：The authors recently published in this journal(SANTOS & al. 2003) the description of a new trace fos-sil, Lacrimichnus SANTOS, MAYORAL & MUNIZ, 2003,ichnogen. nov. They ascribed this ichnotaxon to theencrusting activity of calyptracean gastropods(Crepidula LAMARCK 1799) and ostracean bivalves.However, they not exclude the possibility that the scarsmight have been made by Capulus or Calyptraea. In thecase of the Portuguese and Spanish material, the traceswere made by the Crepidula fossilized with the pectinidbivalves, particularly in view of the fact that no speci-mens of Calyptraea or Capulus were found. The occur-rence in the Atlantic realm (southwestern IberianPeninsula, Portugal and Spain) was dated as LateTortonian (Late Miocene) to Lower Pliocene; similartarces are also known fossil from the Holocene.
