Abstract

The Trwyn y Parc solution pipes on the Isle of Anglesey, Wales, UK are one of only three onshore Miocene fossil flora bearing sites. Here, we revise the palynostratigraphy and present new palaeoclimate data for this geoheritage site. By comparison to palynological data from northern Europe the age has been refined from Miocene to Middle Miocene, possibly Langhian. This is confirmed by palaeoclimate reconstructions comparable to the German Middle Miocene, especially the Langhian after the Middle Miocene Climatic Optimum (MMCO). This new information not only confirms the regional importance of Trwyn y Parc, but shows it to be of national importance. Our findings show that this Regionally Important Geodiversity Site (RIGs) is of national importance as it is the oldest onshore fossiliferous Neogene deposit in the UK. Based on this, and the unique fossil flora preserved at Trwyn y Parc, the site has significant geoheritage value and should be upgraded to Geological Conservation Review (GCR) status and subsequently protected as a Site of Special Scientific Interest (SSSI).

摘要

位于英国威尔士安格尔西岛的 Trwyn y Parc 溶液管道是仅有的三个陆上中新世化石植物群承载点之一。在这里，我们修改了孢粉地层学，并为这个地质遗迹提供了新的古气候数据。与北欧的孢粉学数据相比，年龄已经从中新世提炼到中新世，可能是朗吉阶。与德国中中新世相当的古气候重建证实了这一点，尤其是中中新世气候最佳时期 (MMCO) 之后的朗吉阶。这一新信息不仅证实了 Trwyn y Parc 的区域重要性，而且表明它具有全国重要性。我们的研究结果表明，这个具有区域重要性的地质多样性遗址 (RIG) 具有国家重要性，因为它是英国最古老的陆上新近系化石矿床。基于此，
