Abstract

新发现的双壳类化石命名为Baxoitrigonia baxoiensis gen. et sp. nov.,产地为藏东八宿林卡家东,化石产于景星动物群之下的拉贡塘组下段,同层位有菊石和其他海相双壳类,时代为晚侏罗世Tithonian期;化石的外部特征很接近于三角蛤类Iotrigonia属,但前闭肌痕特征又相似于类三角蚌类,被认为是三角蛤类闯入非海相领域后演变成类三角蚌类的产物。此发现提供了生物和地层两方面的直接证据,证明非海相类三角蚌类(Trigonioidoidea超科)起源于海相三角蛤类(Trigoniida目),而不是起源于珠蚌类(Unionida目)。海相三角蛤类闯入边缘隔绝的洛隆-八宿地区并演变为非海相类三角蚌类,是一次典型的边域成种事件。
