新发现的四翼恐龙是怎样捕鸟的?

from AI思辨日报

1.2亿年前的‘四翼滑翔高手’ 最近,科学家在中国西北的昌马盆地发现了一块非常特别的恐龙化石。这块化石来自1.2亿年前,是一种叫‘建昌马龙’(Jianchangmaensis)的微型迅猛龙。它的大小和一只仓鸮差不多,浑身长满羽毛,而且……它竟然有四只‘翅膀’! 它长得像鸟,但不是鸟 这种恐龙属于‘微迅猛龙’家族,是著名迅猛龙的亲戚。但和电影里光秃秃的迅猛龙不同,微迅猛龙全身覆盖羽毛,前肢和后肢都有长长羽毛,看起来就像有四只翅膀。科学家推测,它们可能像现代的飞鼠一样,在树木之间滑翔。 想一想:为什么恐龙会长出羽毛和翅膀?难道是为了飞行吗? 唯一不在东北的化石 以前发现的微迅猛龙化石几乎都来自中国东北,但这一块却出现在西北的甘肃。更特别的是,这个地方埋藏着很多古代鸟类化石,科学家在这里找到了100多块鸟化石,却只有这一块恐龙化石。为什么?可能是因为恐龙很少掉进湖里,而鸟类更多生活在水边。 肩上的神秘小洞 这块化石保存得非常完好,尤其是肩膀部分的骨头是立体的,而不是压扁的。科学家发现,微迅猛龙的肩骨上有一个小洞,叫做‘喙上孔’,这个洞几乎把骨头分成了两半。这个洞有什么用?可能和飞行有关,但科学家还在研究。 它们吃什么? 微迅猛龙生活在树上,它们很可能以鸟类为食!以前有化石显示,一只微迅猛龙的肚子里有鸟骨头。科学家认为,建昌马龙可能捕食一种叫‘甘肃鸟’的古代水鸟。如果你是一只微迅猛龙,你会怎么捉住一只飞过的鸟儿呢? 为什么这么重要? 这块化石告诉我们,微迅猛龙不仅生活在东北,也生活在更广阔的地区。它还是已知最‘年轻’的微迅猛龙,说明这类恐龙在地球上存在的时间比我们以为的更长。科学家接下来要用CT扫描这块骨头,研究它们的飞行能力。也许,鸟类飞行的秘密就藏在这些恐龙身上!
