查询词典 fossil

WASHINGTON - Scientists unearthed a skull of the most primitive four-legged creature in Earth's history, which should help them better understand the evolution of fish to advanced animals that walk on land. The 365 million-year-old fossil skull, shoulders and part of the pelvis of the water-dweller, Ventastega curonica, were found in Latvia, researchers report in a study published in Thursday's issue of the journal Nature. Even though Ventastega is likely an evolutionary dead-end, the finding sheds new details on the evolutionary transition from fish to tetrapods. Tetrapods are animals with four limbs and include such descendants as amphibians, birds and mammals.

华盛顿-科学家挖掘出一副地球历史上最原始的四足生物头骨，这个有利于帮组他们更好理解鱼类进化成为更先进的陆地行走生物，这个有着三亿六千五百万年年龄的头骨，肩膀和水生生物的一部分骨盆，Ventastega curonica，在Latvia被发现，研究者一篇研究报告发表在在星期三出版的自然杂志上，尽管Ventastega 可能是一个进化的死胡同，这个发现给出了从鱼类到四足动物进化变迁过程的新细节，四足动物是使用四肢的动物并且包括下属的比如两栖类动物，鸟类和哺乳类动物。
