1·Extinct but already fully marine cetaceans are known from the fossil record.

从化石记录中可以了解到一些已经灭绝、但已经完全变成海洋生物的鲸目动物。

2·The fossil record shows that many species have endured for millions of years—so why shouldn't we?

化石记录显示，已经有许多物种存活了数百万年——那么我们为什么不能呢？

3·However, for older sequence of evolutionary development, estimates based on parts in the fossil record.

然而，对于更古老的进化序列，估测则是基于化石记录的部分。

4·Why does the fossil record not document the series of evolutionary changes during the evolution of animals?

为什么化石记录没有记录动物进化过程中的一系列进化变化？

5·I think our discussion of sauropods will illustrate what we can learn by comparing the fossil record to modern animals.

我认为，对蜥脚类动物的讨论将解释我们通过比较化石记录和现代动物所了解到的东西。

6·The fossil record suggests that there was an abrupt extinction of many plants and animals at the end of the Mesozoic era.

化石记录表明，在中生代末期，许多动植物突然灭绝。

7·We can make a very good estimate from the fossil record that humans probably evolved naked skin around a million and a half years ago.

根据化石记录，我们可以更准确地判断出：人类可能在大约150万年前进化出了裸露的皮肤。

8·We find evidence of such extended events in the fossil record, which affords glimpses into the breakup of formerly continuous environments.

我们在化石记录中找到了这种扩展事件的证据，这让我们得以一窥先前一直持续不断的环境分裂现象。

9·Charles Lyell made a good estimate of the Tertiary Period from the fossil record, but his method could not be extended to earlier geological periods.

查尔斯·莱尔根据化石记录对第三纪作出了很好的估计，但他的方法不能扩展到更早的地质时期。

10·Many species appear to remain unchanged in the fossil record for millions of years—a situation that seems to be at odds with Darwin's model of continuous change.

许多物种似乎在数百万年的化石记录中都保持不变——而这种情况似乎与达尔文的持续变化模型不一致。
