Additions to the fauna of the Boom Clay Formation of Belgium (Rupelian, Oligocene).Taxonomic adjustments on the Scyliorhinidae and Rajoidei, discovery of a dasyatidspecies (Pisces, Chondrichthyes) and of a curculionid species (Insecta, Coleoptera)

Large samples of the levels 35,39 and 41 of the Boom Clay Formation (Rupelian, Oligocene, Belgium) were examined. Preliminary prospections (STEURBAUT & HERMAN, 1979) allowed to consider these levels as the richest ones for both teleost and chondrichthyan remains.Despite the bulk of sediment residues sorted, faunistical enrichment is uncredibly poor. The examination of the odontology of recent relative taxa (HERMAN, HOVESTADT-EULER & HOVESTADT, 1990) allows to consider the subgenus Bythaelurus as a genus of the subfamily Pentanchinae. Scyliorhinus aff. coupatezi is attributed to the gen... Mehr ...
