6600多万年前，一种可怕的动物漫步在地球上。它极其残忍，被称为“地狱鸡”。 这种动物站起来10英尺(约合3米)高，因长着鸡一样的头冠、羽毛翅膀、长爪、极具攻击力的嘴和一条强有力的尾巴，而得到这个名字。它的学名叫Anzu wyliei。美国犹他大学古生物学家在南达科他州和北达科他州的古老岩石中发现这种动物的3副部分骨架。
% E. x5 h: T7 I& W* d& F5 y9 T$ b1 g- U2 D: ~
他们把这3部分化石拼凑在一起，发现这些分开的骨骼刚好形成一副近乎完整的恐龙骨架。犹他大学生物学博士后研究生艾玛-沙赫纳表示：“它是一种巨型猛禽，但长着鸡一样的头部和想必是羽毛的东西。这种动物站起来高约10英尺，非常恐怖。” 匹兹堡卡内基自然历史博物馆的马特-拉曼纳说：“我们开玩笑似地把这种动物叫做地狱鸡。我想这是一个非常适合它的名字。我们把它叫做Anzu，这是古代神话中像鸟一样的恶魔。” ; q# [3 W* d& T, A$ E2 l

6600万年前，一种45英石(约合286千克)重的野兽漫步在达科他山上，它们和最可怕的食肉动物雷克斯霸王龙生活在同一时期。Anzu wyliei颇似一种不能飞的巨鸟，长有细长脖子和鸵鸟一样的后肢。在南达科他州和北达科他州的古老岩石中发现的化石只有骨骼，但科学家发现的其他化石显示这种恐龙的近亲长有羽毛，这强有力的证明了Anzu wyliei也有羽毛。这种恐龙是杂食动物，吃植被和小动物，或许也吃蛋。科学家认为，它之所以进化出如此高大的身体，是为抵御更大捕食者。 5 p! o0 P# A2 |; ^9 M, @: }
