A total of 557 shells of the gastropod species Persististrombus latus (Gmelin, 1791) from several late Pleistocene deposits in the island of Mallorca (Balearic Islands), are studied. Six ichnogenera related
to bioerosion have been recognised: Entobia, generated by clionaid sponges; Gastrochaenolites, produced by lithophagous bivalves; Caulostrepsis and Maeandropolydora, borings of spionid polychaetes; Renichnus,caused by the fixation of vermetid gastropods and serpulid polychaetes; and durophagous scars. This assemblage has been identified to belong to the Entobia ichnofacies, typical of shallow marine bottoms since the Mesozoic. Moreover, the analysis of the proportions of each ichnogenus in the respective deposits has allowed to extract palaeoenvironmental information related to the water clearness.
