摘要
摘要西伯利亚外贝加尔东部(Zabaykalsky Krai)寒武系2中Bystraya组的岩屑动物群，包括至少17个已描述的分类群，分布在水石目和正石目之间。种Microcornus、Parkula Conotheca, Neogloborilus Cupitheca从寒武纪地层广泛报道的地方。只在外贝加尔湖地区发现了uslonica Triplicatella。Dauritheca被提议作为较低级同音词Pachytheca的替代属名，Pachytheca最初描述自中国新疆，其范围扩展到外贝加尔湖。有突出的边缘肋的海螺被称为达乌里卡Salanytheca daurica sp. nov.，这是一个在蒙古和西伯利亚北部早寒武纪已知的属。John S.

Hyoliths from the Bystraya Formation (Cambrian Series 2) of eastern Transbaikalia (Zabaykalsky Krai), Siberia
Abstract The hyolith fauna of the middle Bystraya Formation (Cambrian Series 2) of eastern Transbaikalia (Zabaykalsky Krai), Siberia, includes at least 17 described taxa distributed between the orders Hyolithida and Orthothecida. Species of Microcornus, Parkula, Conotheca, Neogloborilus and Cupitheca are widely reported from Cambrian strata elsewhere. Triplicatella uslonica sp. nov. is known only from Transbaikalia. Dauritheca is proposed as a replacement generic name for the junior homonym Pachytheca, originally described from Xinjiang, China, and its range is extended to Transbaikalia. A conch with prominent comarginal ribs is referred to Salanytheca daurica sp. nov., a genus otherwise known from the early Cambrian of Mongolia and northern Siberia. John S.
