A late Changhsingian bivalve complex including species from the genera Palaeonucula, Dacryomya, Malletia ?, Sarepta ?, Myalina, Pteria, Maitaia, and Unionites is discovered in northeastern Asia for the first time. The transition from the Permian to the Triassic in high-boreal basins has been shown to include two extinction episodes similar to those observed in the low-boreal basins and apparently evoked by trap volcanism activation in Siberia. Changes in benthic foraminifera diversity and vertical distribution of ammonoidea of the genus Otoceras in transitional Permian-Triassic deposits also are considered. Images of bivalves from the most typical taxa are presented.
首次在亚洲东北部发现了一个长兴期末期的双壳类组合，其中包括古胡桃蛤属、泪蛤属、马莱蒂蛤属（？）、萨雷普塔蛤属（？）、褶翅蛤属、翼蛤属、迈泰蛤属和似珠蚌属的物种。高北极地区盆地从二叠纪到三叠纪的过渡已被证明包括两个灭绝事件，这与在低北极地区盆地观察到的灭绝事件相似，显然是由西伯利亚的陷阱火山活动激活引起的。还考虑了二叠纪 - 三叠纪过渡沉积物中底栖有孔虫多样性的变化以及耳菊石属菊石的垂直分布。展示了最典型分类群的双壳类图像。
