摘要

发现于一个多世纪前,不列颠哥伦比亚省东南部的下寒武统(系列2,阶段4)Cranbrook Lagerstätte是北美最古老的伯吉斯页岩型矿床之一。这个Konservat-Lagerstätte富含榄叶三叶虫,但也产生了一个非常低多样性的软体化石组合,包括Tuzoia和Anomalocaris,以及一个低多样性的鱼动物群。然而,对它的科学研究仍然有限。2015年,皇家安大略博物馆进行了实地调查,揭示了该遗址的生物群、沉积环境和地学条件的新信息。Cranbrook Lagerstätte不仅对早寒武纪生物地层学和与其他伯吉斯页岩型矿床的比较具有重要意义,而且还揭示了寒武纪远端外陆架环境中一些鲜为人知的生物多样性。补充资料:https://doi.org/10.6084/m9.figshare.c.6850810

The lower Cambrian Cranbrook Lagerstätte of British Columbia
Discovered over a century ago, the lower Cambrian (Series 2, Stage 4) Cranbrook Lagerstätte of southeastern British Columbia's Eager Formation is one of the oldest Burgess Shale-type deposits in North America. This Konservat-Lagerstätte is rich in olenelloid trilobites, but also yields a very low-diversity soft-bodied fossil assemblage including Tuzoia and Anomalocaris , and a low-diversity ichnofauna. Its scientific study, however, remains limited. A 2015 field-based investigation by the Royal Ontario Museum has revealed new information about the site's biota, depositional environment, and taphonomic conditions. Not only is the Cranbrook Lagerstätte significant for early Cambrian biostratigraphy and comparisons with other Burgess Shale-type deposits, it also reveals some of the little-known diversity of life along a distal outer shelf environment during the Cambrian period.

期刊介绍: Journal of the Geological Society (JGS) is owned and published by the Geological Society of London. JGS publishes topical, high-quality recent research across the full range of Earth Sciences. Papers are interdisciplinary in nature and emphasize the development of an understanding of fundamental geological processes. Broad interest articles that refer to regional studies, but which extend beyond their geographical context are also welcomed. Each year JGS presents the ‘JGS Early Career Award'' for papers published in the journal, which rewards the writing of well-written, exciting papers from early career geologists. The journal publishes research and invited review articles, discussion papers and thematic sets.
