数年来,古生物学家一直想知道蛇颈龙是否也通过怀胎方式繁殖后代。
Now they have found out that it wasbut with an interesting twist.
如今他们证实了这一点但却是以一种有趣的方式。
Robin O Keefe of Marshall University in West Virginia has analysed a plesiosaur fossil found inKansas in 1987, which palaeontologists had suspected was a pregnant female about 4.7metres long, but which had not been cleaned up and studied until last year.
西弗吉尼亚州马歇尔大学的罗宾奥基夫对1987年在堪萨斯州发现的蛇颈龙化石进行了分析,此前,古生物学家一直怀疑它是一条身长4.7米雌性怀孕蛇颈龙, 但直到去年才将其清理和研究完毕。
As he reports in Science, he found an array of tiny bones, apparently belonging to a smallspecimen of the same species, in the fossil s abdominal cavity .
奥基夫在《科学》杂志报告中指出,在蛇颈龙化石腹腔内发现了一些小骨骼阵列,它们显然是属于同类物种的小标本。
It is unlikely that these were the remains of a meal because the bones are not broken downin the way that would be expected if they were partly digested.
这些小骨骼不可能是食物的残渣,因为如果它们是被部份消化的其它动物的骨骼,那么它们的断裂方式应该研究人员所预想的方式相同,但结果却不是。
