據專傢介紹，在英國威爾士中部發現瞭世界上最重要的化石沉積層之一。新發現的化石數量多，遺址位於波伊斯郡蘭德林多德威爾斯附近。為瞭開展工作，研究人員不得不籌資購買顯微鏡設備。
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.
威爾士國傢博物館的研究人員們在4.6億多年前威爾士中部被海洋覆蓋時埋在海底的巖石中發現瞭這些化石。研究人員說，他們在私有土地上的一個秘密地點發現瞭170多個物種的化石。
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.
這些化石包括多種軟軀體生物，化石中的軟組織和完整有機體均得以保存，而不僅僅是生物的外殼和骨骼，這實屬罕見。事實上，世界上隻有一處奧陶紀遺址化石存留下瞭接近這種程度的細節，該遺址位於摩洛哥。
Researchers say the discovery is important as it gives a fresh insight into how life evolved during this period.
研究人員說這一發現的意義重大，因為它為研究這一時期的生命進化方式提供瞭新的見解。
