原标题:北极发现九千万年前鸟类化石体型巨大可能会潜水
参考消息网12月23日报道俄媒称,学术期刊《科学报告》发表文章称,美国罗彻斯特大学古生物学家在北极发现距今约9000万年前的鸟类骨骼化石。
俄罗斯卫星网12月21日报道,这些遗骸是在加拿大阿克塞尔海伯格岛上发现的。据科学家评估,骨骼化石全长12厘米,也就是说这种远古鸟类体型相当大,被称为Tingmiatornis arctica。
根据推测,这种鸟会游泳和潜水,以鱼为食,可吃下长达半米的鱼。分析显示,这种鸟距今已有9000万年历史。科学家认为,这验证了关于当时北极曾是温暖气候的假设。
据估算,在远古时代北极的年均气温为14摄氏度,夏季最高气温达35度。对同样在阿克塞尔海伯格岛上发现的远古贝壳的分析数据也能证明这一点。
