Abstract

The Upper Silurian exposures on Saaremaa Island, mostly represented by small coastal cliffs, are the best in Estonia. Among these exposures are two coastal cliffs that are in many ways unique. The Pridoli crinoid fauna at Kaugatuma and the Ohesaare cliffs contains several endemic genera such as Methabocrinus, Saaremaacrinus, and Velocrinus, which occur exclusively in the Pridoli of Saaremaa Island. These localities have great potential for future studies of crinoid paleobiology and paleoecology. The fossil symbiotic associations have high value for studies devoted to evolutionary paleoecology. The Kaugatuma and Ohesaare cliffs yield the only symbiotic associations that are known from the Pridoli worldwide. Both cliffs are also famous localities of early vertebrates. The Kaugatuma and Ohesaare cliffs are places of scenic beauty, and the rarity of fossiliferous Pridoli outcrops in the Baltic Sea region makes these cliffs important destinations for European geotourism.

索夫半岛（爱沙尼亚萨雷马岛）上两处极具价值的地质遗迹：了解独特晚志留纪动物群的窗口

萨雷马岛的上志留纪岩层主要以小型海岸悬崖为代表，是爱沙尼亚最好的岩层。在这些岩层中，有两处海岸悬崖在许多方面都是独一无二的。Kaugatuma 和 Ohesaare 悬崖上的 Pridoli 板鳃动物群包含几个特有属，如 Methabocrinus、Saaremaacrinus 和 Velocrinus，这些属只在萨雷马岛的 Pridoli 出现。这些地方对未来研究棘皮动物古生物学和古生态学具有巨大潜力。共生关系化石对于古生态进化研究具有很高的价值。Kaugatuma和Ohesaare悬崖出土的共生组合化石是全世界已知的唯一来自普里多利的共生组合化石。这两处悬崖也是早期脊椎动物的著名产地。考加图马悬崖和奥赫萨雷悬崖是风景优美的地方，波罗的海地区罕见的普里多利化石露头使这些悬崖成为欧洲地质旅游的重要目的地。

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.
