劍橋郡一采石場內發現瞭英國境內最大的恐龍行跡遺址。研究人員在石灰巖地面上辨認出瞭大約 200 個互相重疊交錯的巨大腳印，這些腳印形成於約 1.66 億年前。
The dinosaur tracks were first discovered by a worker at the quarry. Scientists have now unearthed 200 huge footprints criss-crossing the limestone floor. They were made by two different types of dinosaurs. Giant long-necked sauropods left one-metre-wide circular prints, while smaller three-toed marks were created by the carnivorous Megalosaurus.
這些恐龍的足跡最初被一名采石場的工人發現。科學傢目前已經在石灰巖地面上挖掘出瞭 200 個重疊交錯的巨大腳印。這些腳印來自於兩種不同的恐龍。體型巨大的長頸蜥腳類恐龍留下的是直徑一米寬的圓形腳印，而另外一種較小的三趾腳印則來自於肉食性的巨齒龍。
Scientists aren’t sure how they were preserved but think the footprints were perhaps covered with sediment during a storm. Some tracks extend for 150 metres but could reach even further under parts of the quarry not yet excavated.
科學傢們不能確定這些腳印是如何被保存下來的，但他們認為這些腳印可能是被一場風暴中的沉積物所掩蓋。一些行跡延續瞭 150 米，但還可能會繼續延伸到采石廠中尚未被挖掘的部分。
