含有化石的

As the wide existence of steady liquid water on the red planet has been more and more clearly proved ,and the idea that bacterielles fossil was brought to the earth by an aerolite from the Mars was incessantily debated over ,the argument concerning whether this planet witnessed the existence of organism which lives till now will be more fierce.

由于越来越多的证据表明红色行星上曾经含有大量稳定的液态水，由于人们对细菌化石是火星上的一块陨石带到地球上的这种观念争议不休，因此，有关该行星上是否曾经存在生命以及生命是否持续到今天的争论更加激烈。

Thus, it can be inferred that the Selong Group in the southern Tibet is also Lopingian in age in view of its correctable brachiopod faunas with those of the Kalabagh Member of the upper Wargal Formation and the Chhidru Formation and the conodont zones around the Permian/Triassic boundary in southern Tibet.

我国西藏南部色龙群及相当地层含有与巴基斯坦盐岭地区Kalabagh段和Chhidru组可对比的乐平世腕足动物群以及二叠系—三叠系界线附近连续的牙形类化石带，由此可以推定色龙群的时代应为乐平世。

The northern part of the park is called the Painted Desert and includes areas of the multi-hued badlands, while the southern part of the park contains heavy concentrations of fossilized wood and American Indian petroglyph sites.

公园的北部被称为彩绘沙漠，包括多领域斑驳陆离荒地，而公园南面的含有重金属浓度的化石木，美洲印第安人岩石壁画的网站。

Volcanic ash settles quickly to form extensive beds of tuff, many of which contain perfectly preserved fissils .

火山灰迅速降落形成了大面积的凝灰岩岩层，其中很多岩层含有保存完好的化石。

Dr Allwood showed that her stromatolites, which are 3.4 billion years old, contain seven different, but regularly recurring patterns ranging from "cuspate swales" to "egg-carton laminites".

Allwood博士指出在她所研究的具有34亿年历史的层叠岩石化石中，发现含有有规则重复出现的七种，从&尖芦苇&到&蛋箱分层&等结构。

The Pennsylvanian strata contain abundant benthos fossoils, including kinds of reef-building organisms. These reef-building organisms built different reefs in which the main typs are Fomitchevella coral framework reefs, phylloid algae framework-barrier reefs, Ivanovia cf.

宾夕法尼亚亚纪地层中含有极为丰富的底栖生物化石，其中包括多种造礁生物并建造了不同类型的生物礁，主要礁体有：Fomitchevella珊瑚骨架礁、叶状藻骨架－障积礁、Ivanovia cf。

Moreover , an X-ray analysis of the regions of the feathers containing these bodies showed them to be composed mainly of carbon -as would be expected if they were fossilised melanosomes .

而且，对含有该结构的羽毛区域的X射线分析显示，它们主要由碳元素组成--而如果它们是黑色素体化石，就正和预想的一样。

It dates to the very early Cambrian period and it also contains only soft-bodied forms.

它造于寒武纪的早期，并且异样只含有软体植物化石。

Perhaps another ancient fossil bed of soft-bodied animals from 00-million-year-old seas is awaiting discovery.

或者另一些含有来自于亿年前的陆地植物的化石亟待发现。

Todd entura of the Uniersity of Illinois-Chicago will describe what may be the earliest archaean fossil eidence yet discoered-rock samples that are 2.71 billion to 2.65 billion years old that were collected from a deep underground gold mine in Ontario, Canada.

Todd entura将描述迄今为止发现的最早的古化石证据――在加拿大安大略省某地下深层金矿中发现的距今约27亿1千万年到26亿5千万年岩石标本。entura于他的同事发现该岩石中含有一种类脂，或者说是一种含油化合物，这种类脂只存在于古细菌细胞膜中。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
