科學傢在蒙古戈壁沙漠發現瞭一種罕見的新兩指恐龍。雖然這種恐龍長有鋒利的長爪，但科學傢認為它們並不是兇猛的掠食者。
Therizinosaurs lumbered around the Earth on their hind legs tens of millions of years ago. Some researchers have likened them to giant feathered sloths. Every species discovered so far had three fingers with strikingly long claws on each hand. But this new discovery in Mongolia only had two.
鐮刀龍是一類在數千萬年前的地球上用後肢緩慢行走的恐龍。一些研究人員把它們比作巨大的長有羽毛的樹懶。在此之前發現的每種鐮刀龍每隻手上都有三個指，每個指上都長有醒目的長爪。但本次在蒙古發現的新品種隻有兩個指。
At about three metres in length and weighing more than a quarter of a ton, it was a medium sized dinosaur. And despite their sharp claws’ nightmarish appearance, this reptile was not a predator. Instead, it’s thought to have used its hands to grasp vegetation.
這種鐮刀龍體長三米，體重超過四分之一噸，屬於中型大小的恐龍。雖然它們的利爪看起來頗為可怕，但這種爬行動物並非掠食者。科學傢認為它們其實是用手來抓取植物而非獵物。
