查询词典 Palaeocene

Our record shows a palaeoenvironmental transition from a warm 'greenhouse' world, during the late Palaeocene and early Eocene epochs, to a colder 'icehouse' world influenced by sea ice and icebergs from the middle Eocene epoch to the present.

我们的记录显示一幕由古老环境由处于旧世纪晚期和新世纪早期温暖的'温室'世界向由从新世纪中期到目前由海冰和冰山造成的比较寒冷的'冰室'世界转变。

This number is "very conservative" and could be as high as 11 metres, Greene says, which would lower the corresponding temperature estimate for the Palaeocene tropics.

这个数据很保守，也可能是11米，格林尼说，这将有可能降低古新世时代热带地区的气候。

As might be expected, the genes suggest that the pace of change hots up after the end of the Palaeocene, resulting in the sort of species illustrated above.

如我们所料，遗传基因的研究发现到古新世时代末期之后的一些变化，这就是物种进化的速度急速加快，也就导致了以上提及的成百上千的物种。

The characteristic Palaeocene faunaseems to have come and gone with the ancestors of modern mammals still skulking unchanged in their burrows.

那些独特的古新代的动物群一定是跟随着现代哺乳动物的老祖宗跑到巢穴里享受着偷欢的情趣，以至自身丝毫未变。

The Cretaceous—the last period when dinosaurs ruled the roost—was followed by the Palaeocene.

恐龙主宰世界的最后一个时期是白垩纪时代，之后就进入了古新代。

The results support the idea that the temperature difference between the Palaeocene tropics and higher-latitude regions was as large as it is today, even though the higher latitudes were much warmer during that time.

这个结果与古新世和高纬度地区的气温差别相符。尽管那时纬度高的地方要相对暖和一些。

This number is "very conservative" and could be as high as 11 metres, Greene says, which would lower the corresponding temperature estimate for the Palaeocene tropics.

这个数据很保守，也可能是11米，格林尼说，这将有可能降低古新世时代热带地区的气候。呵呵，明明是蛇化石，你却只说&蛇&，把大家都骗进来了。

Using models1 based on the largest modern-day snakes and their estimate of the Titanoboa's size, the team calculated how hot the tropics must have been 58 to 60 million years ago, a period known as the Palaeocene.

制作的模型是根据现在最大的巨蟒和他们估计的泰坦神族巨蟒的尺寸为依据，这个小组又计算出了五千八百万-六千万年前的热带气候，被称作古新世时期。

As to what happened to the Palaeocene fauna, the evidence points not towards an errant asteroid but to a giant burp from the oceans, which released a huge amount of methane.

至于古新世时代末期动物群到底发生了什么致使它们灭绝，有证据指出这是海洋的一个惊涛骇浪所散发出的大量甲烷气体所致使的，而并没有提到所谓的偏轨行星。

It is divided intoseven structure-palcohydrogcology periods. The ancient hydrodynamic field andpaleohydrogeochemical field in Palaeocene are studied.

着重研究了盆地古新世时古水动力场和古水文地球化学场，指出沉积水初始迁移阶段的成矿作用主要是在沉积承压水系统区与渗入木承压水系统之间的过渡层状压力带。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
