摘要

从纽芬兰上岛湾镇的一个地点确认了 250 多件属于埃迪卡拉生物群的化石。这些化石保留了高浮雕、亚毫米形态细节,为我们进一步了解一些最早的埃迪卡拉生物提供了机会。与许多其他埃迪卡拉纪地点不同的是,该地点的地质遗产由于位于镇内且靠近海洋,面临着受到人类和环境事件严重影响的风险。作为为期一年的研究的一部分,我们安装了照相机来记录可能对化石表面造成影响的有害事件。在遗址上发现了罕见的高影响人为事件,如破坏行为,以及因鞋履不整和不当活动而造成的潜在意外损害。环境事件更为常见,高能量的海浪覆盖表面,冬季形成的冰层多次吞噬化石,对化石造成破坏的风险很高。目前正在努力实施地质保护方法,以减轻该遗址面临的挑战,并最大限度地减少未来的损害。其中一些方法可能适用于世界各地其他面临风险的化石地点。

Protecting Newfoundland’s Palaeontological Geoheritage: Mitigating Anthropic and Environmental Damage to the Ediacaran Fossils of Upper Island Cove

Over 250 fossils belonging to the Ediacaran biota have been recognised from a single site in the town of Upper Island Cove, Newfoundland. These fossils preserve high-relief, sub-mm morphological detail providing an opportunity to further our understanding of some of the earliest Ediacaran organisms. Unlike many other Ediacaran localities, the geoheritage of this site is at risk to both high impact anthropic and environmental events due to its location within the town and close proximity to the ocean. As part of a year-long study, cameras were set up to record potentially deleterious events impacting the fossiliferous surface. Rare high impact anthropic events such as vandalism have been noted at the site, alongside the potential for inadvertent damage caused by misuse through poor footwear and inappropriate activities. Environmental events are more common and present a high risk of damage to the fossils through high-energy waves covering the surface and the formation of sheets of ice during the winter that engulf the fossils on numerous occasions. Work is now underway to implement geoconservation methods that will mitigate the challenges that the site faces and minimise any future damage. Some of these methods may be pertinent to other at-risk fossil localities found across the world.

期刊介绍: The Geoheritage journal is an international journal dedicated to discussing all aspects of our global geoheritage, both in situ and portable. The journal will invite all contributions on the conservation of sites and materials - use, protection and practical heritage management - as well as its interpretation through education, training and tourism. The journal wishes to cover all aspects of geoheritage and its protection. Key topics are: - Identification, characterisation, quantification and management of geoheritage; - Geodiversity and geosites; - On-site science, geological and geomorphological research: - Global scientific heritage - key scientific geosites, GSSPs, stratotype conservation and management; - Scientific research and education, and the promotion of the geosciences thereby; - Conventions, statute and legal instruments, national and international; - Integration of biodiversity and geodiversity in nature conservation and land-use policies; - Geological heritage and Environmental Impact Assessment studies; - Geological heritage, sustainable development, community action, practical initiatives and tourism; - Geoparks: creation, management and outputs; - Conservation in the natural world, Man-made and natural impacts, climate change; - Geotourism definitions, methodologies, and case studies; - International mechanisms for conservation and popularisation - World Heritage Sites, National Parks etc.; - Materials, data and people important in the history of science, museums, collections and all portable geoheritage; - Education and training of geoheritage specialists; - Pedagogical use of geological heritage - publications, teaching media, trails, centres, on-site museums; - Linking the United Nations Decade of Education for Sustainable Development (2005- 2014) with geoconservation.
