Conidae and Terebridae (Gastropoda: Neogastropoda) from the Plio-Pleistocene of the Philippines

摘要

Six species of Conidae and seven species of Terebridae are reported from the Plio-Pleistocene "Cabarruyan" fauna of Pangasinan, the Philippines. Eleven species are identified; these species all occur in the Recent Indo-Pacific fauna and seven of these are previously known from the fossil record as well. The species composition of this fauna shows little overlap with other fossil assemblages, except with the Fijian fossil assemblage. This is attributed to a lack of knowledge on Indopacific fossil faunas as well as to the relatively deep water setting (200-300 m) of this fauna. More research is needed to determine why the Fijian assemblage is relatively similar.
