第2010期:Very rare 460-million-year-old fossils discovered

Researchers at Amgueddfa Cymru – Museum Wales – found the fossils in rocks which were laid down under the sea more than 460 million years ago when mid Wales was covered by an ocean. They say more than 170 species were uncovered at a secret location on private land. 威尔士国家博物馆的研究人员们在4.6亿多年前威尔士中部被海洋覆盖时埋在海底的岩石中发现了这些化石。研究人员说，他们在私有土地上的一个秘密地点发现了170多个物种的化石。 The fossils include many soft-bodied creatures, where soft tissue and complete organisms have been preserved, rather than just shells and bones. That's extremely rare. In fact, there's only one other Ordovician site in the world which preserves close to this level of detail – in Morocco. 这些化石包括多种软躯体生物，化石中的软组织和完整有机体均得以保存，而不仅仅是生物的外壳和骨骼，这实属罕见。事实上，世界上只有一处奥陶纪遗址化石存留下了接近这种程度的细节，该遗址位于摩洛哥。 Researchers say the discovery is important as it gives a fresh insight into how life evolved during this period. 研究人员说这一发现的意义重大，因为它为研究这一时期的生命进化方式提供了新的见解。 词汇表fossils 化石soft-bodied 软躯体的tissue （动植物的细胞）组织organisms 有机体，生物Ordovician 奥陶纪的insight 了解，深刻见解
