These findings are not of Precambrian animals themselves, but of their tracks. And these,paradoxically, may be more useful.
发现的并不是寒武纪前的动物本身,而是它们的足迹。而出人意料的是,这些足迹可能还更有用。
Alexander Liu of Oxford University and his colleagues took an interest in Mistaken Pointbecause it is a site known for so-called Ediacaran fossils, shell-less animals of unknownprovenance that slightly predate the Cambrian.
牛津大学的亚历山大?刘和他的同事们之所以对错误点产生兴趣,是因为它因埃迪卡拉动物化石而闻名,埃迪卡拉动物是存在于略早于寒武纪时期的缘起不明的无壳动物。
As Mr Liu and his team explored the rocks they came across more than 70 markings thatlooked like tracksslight impressions in the sediment with tiny ridges sticking up along thesides.
在刘和他的团队对那里的岩石进行勘察的过程中,他们发现了70多个类似足迹的斑点在沉淀物中的一些浅痕,其周边有轻微的突起。
These markings, they report in Geology, are up to 13mm wide and up to 17cm long.
据他们在《地质学》杂志中的报告,这些斑点宽不过13毫米,长不过17厘米。
What is most curious about these tracks is that the rock they are in is reckoned to haveformed at least a kilometre below sea level.
