摘要
自19世纪后期以来,葡萄牙中西部独特的上新世海洋动物群就已为人所知。它们包括高度多样化的软体动物,对它们的研究还远未完成。近40年前发现的Vale do Freixo (Carnide, Pombal)可能是最杰出的化石遗址。尽管如此,双壳类动物仍然相对不为人所知。本文对这一相关类群的海洋软体动物进行了分类研究。这项研究基于对食肉动物组的三个化石层的详细采样,得出了32科75属85个物种的名单。在Carnide地区发现了43种新物种,在葡萄牙上新世首次报道了23种,使贝拉沿岸Mondego盆地的已知物种数量增加到115种。
Pliocene marine Bivalvia of Vale do Freixo (Pombal, Portugal): updated taxonomic list and discussion
The exceptional Pliocene marine faunal assemblages of west central Portugal have been known since the late 19th century. They include highly diverse molluscan faunas whose study is far to be completed. Discovered nearly 40 years ago, Vale do Freixo (Carnide, Pombal) is perhaps the most outstanding fossil site. Neverthless, the bivalves remain relatively unknown. This study focuses on the taxonomy of this relevant group of marine Mollusca. The research, based on a detailed sampling of three fossiliferous beds from the Carnide Formation, yielded a list of 85 species belonging to 75 genera and 32 families. Forty-three species are new for the Carnide area and twenty-three are reported for the first time in the Portuguese Pliocene, increasing to 115 the number of known species in the Mondego Basin in the Beira Litoral.
