摘要

报道了在俄罗斯中部乌拉尔地区靠近Lysaya山南坡的Shyrokovsky湖岸暴露的Ediacaran Chernyi Kamen组中新发现的Palaeopascichnus、Mawsonites、Hiemalora和迄今为止未知的rangemorph生物。含化石层位与Ust’-Sylvitsa组上覆层的绝对沉积年龄（563±3.5 Ma）进行了地层对比。这些埃迪卡拉类软体化石的发现，不仅加深了我们对其时间和古地理范围的认识，而且表明了多年来一直被忽视的中乌拉尔埃迪卡拉纪的古生物学潜力尚未完全实现。

A new occurrence of Ediacara soft-bodied biota in the Central Urals, Russia

A new occurrence of Palaeopascichnus, Mawsonites, Hiemalora and hitherto unknown putative rangeomorph organisms is reported from the Ediacaran Chernyi Kamen Formation exposed on the coast of Lake Shyrokovsky near southern slope of Mount Lysaya in Central Urals, Russia. The fossil bearing horizon stratigraphically correlated with absolute depositional age of 563 ± 3.5 Ma obtained from the overlying horizon in Ust’-Sylvitsa Formation. These findings of Ediacara-type soft-bodied fossils not only develop our understanding of their temporal and paleogeographic range, but also demonstrate that palaeontological potential of the Ediacaran of Central Urals, which was remained unattended for many years, has not entirely been realised.

期刊介绍： Gondwana Research (GR) is an International Journal aimed to promote high quality research publications on all topics related to solid Earth, particularly with reference to the origin and evolution of continents, continental assemblies and their resources. GR is an "all earth science" journal with no restrictions on geological time, terrane or theme and covers a wide spectrum of topics in geosciences such as geology, geomorphology, palaeontology, structure, petrology, geochemistry, stable isotopes, geochronology, economic geology, exploration geology, engineering geology, geophysics, and environmental geology among other themes, and provides an appropriate forum to integrate studies from different disciplines and different terrains. In addition to regular articles and thematic issues, the journal invites high profile state-of-the-art reviews on thrust area topics for its column, ''GR FOCUS''. Focus articles include short biographies and photographs of the authors. Short articles (within ten printed pages) for rapid publication reporting important discoveries or innovative models of global interest will be considered under the category ''GR LETTERS''.
