In some books, too, you will find the tertiary and quaternary taken out and replaced by periods of different lengths called the Palaeogene and Neogene.

在有书里，你还会发现不用第三纪和第四纪，而是用不同长度系来取而代之，称做第三系和上第三系。

And, we would expect that, back in the Miocene, there were little pods of sperm whales, and we might also suppose that if they came under attack they might try to help defend each other.

So, you know, with the comet impact, the K-T boundary, certainly, you know, lots of niches opened up, and that's why we're here, right?

所以你知道， 随着彗星撞击，白垩纪-第三纪界线形成，确实有很多生态位空了出来，这就是我们存在原因，对吧？

In some books, too, you will find the tertiary and quaternary taken out and replaced by periods of different lengths, called the Paleogene and Neogene.

在一些书, 你会发现第三纪和第四纪被取出, 取而代之是不同长度时期, 称为古近纪和新近纪。

The one extinction that almost everybody is familiar with is the K-T or cretaceous tertiary extinction.

几乎每个人都熟悉一次灭绝事件是K-T灭绝，也称为白垩纪-第三纪灭绝事件。

To be precise, we will be going back 66 million years ago to an event known as The Cretaceous–Paleogene extinction event, which is also known as the Cretaceous–Tertiary or K–T extinction.

准确地说， 我们将回到 6600 万年前白垩纪-古近纪灭绝事件，也称为白垩纪-第三纪或 K-T 灭绝事件。

Why this should be so we do not know; nor why the later tertiary periods should have been much more favourable for their existence than the present time.

数量之多无可比拟。 为什么会这样我们不知道； 也不知道为什么后来第三纪时期应该比现在更有利于它们存在。

She collected samples from eight KT boundary sites, from New Mexico in the south right up into western Canada.

她从8个布有第三纪界线层地点采集样本，从南部新墨西哥一直到加拿大西部。

The one that I want to talk more about specifically is the K-T extinction or the cretaceous tertiary extinction.

我特别想详细讨论是K-T灭绝事件，也称为白垩纪-第三纪灭绝事件。
