化石的

According to the principle of strontium isotope stratigraphy, we attempt to determine the age of the boundaries for Campanian/Santonian and Maastrichtian/Campanian by 87Sr/86Sr ratios for Gamba section in southern Tibet.

在与国际上同期海相地层锶同位素演化曲线对比的基础上，研究了晚白垩世海相碳酸盐锶同位素组成与主要地质事件的关系；在将本研究锶同位素数据融入到全球中新代海水锶同位素曲线的基础上，综合作出了中新生代海平面变化和锶同位素对照曲线，讨论了全球风化速率，造山事件，气候，海平面变化以及灾变性事件对中新生代海水锶同位素的控制作用；根据锶同位素地层学原理，本研究尝试将碳酸盐锶同位素组成用于海相地层定年上，利用已有的全球海水87Sr/86Sr值-年龄数据库和测试的藏南晚白垩海相碳酸盐的87Sr/86Sr值，确定了岗巴剖面Campanian/Santonian和Maastrichtian/Campanian阶界线，标定了广泛分布于白垩纪的厚壳蛤化石的年龄；本研究还将这些方法推广到了塔里木盆地井下奥陶纪地层的年龄标定，确定了中/上，中/下奥陶统界线，从锶同位素角度获得了古岩溶作用证据，显示锶同位素地层学在解决海相地层对比，年龄确定及在岩溶型油气储层研究中的潜在价值和良好应用前景。

In anatomy he studied the circulation of the blood and the action of the eye. He made discoveries in meteorology and geology, learned the effect of the moon on the tides, foreshadowed modern conceptions of continent formation, and surmised the nature of fossil shells. His scheme for the canalization of rivers still has practical value and he probably devised the hydrometer.

解剖学方面，他对血液循环和眼有着较深入的研究；气象学和地理学方面，它也表现出了卓越的才华：他认为海洋的潮汐形成与月球的运动密切相关；他提出的陆地形成观念与现代理论颇为相似；他还还对化石的形成和成分进行了有根据的猜测；他设计并亲自主持修建的运河灌溉工程时至今日仍然有实际的应用价值，而在此过程中他可能设计出了液体比重计的雏形。

It provides for visitors with browsing and enjoying l marine life fossil, such as Ammonite fossil, Orthoceras fossil, Traumatocrinus crinoid fossil, Algae fossil, Shrimp fossil, Apateon pedestris, Eurypterid fossil etc.

Lesson1 Finding fossil man发现化石人 We can read of things that happened 5,000 years ago in the Near East,where people first learned to write.But there are some parts of the world where even now people cannot write.The only way that they can preserve their history is to recount it as sagas-legends handed down from one generation of storytellers to another.

通过在近东的那些第一个学会书写的人们的记录，我们可以知道五千年前发生在近东的事，但是，到现在为止世界上仍然有一些地区的人们不会书写，他们能够保存他们的历史的唯一方法就是把它当作英雄故事或传奇来一代一代的通过讲故事的人们流传下来。

SEM observation of the earliest skeletal fossils from the late Sinian Dengying Formation in southern Shaanxi, China indicates that the tube wall of Sinotubulites levis is encrusted by phosphate spherical and filamentous structure, possibly reflecting microbially mediated phosphatization of tube wall. Three preservational microfabrics detected, namely mat-like structure formed by intertwining of rigid filaments, densely packed spheres with a distinctive framboidal external surface and hollow centers and tightly packed spherical bodies with extremely smooth external surface, may refer to different types of mineralized cyanopytes.

陕南晚震旦世高家山生物群中骨骼化石的电镜扫描显示，Sinotubulites levis壳壁中具有丰富的磷酸盐化球状和丝状体，可分为3种不同类型的微生物组构：1由相互缠绕的丝状体所组成的藻席状组构；2由外表面成莓球状，内部中空的球状体紧密堆叠所形成的组构类型；3由表面极为光滑的球状体堆叠所形成的组构。

"Pterosaur Huanjiang" Maybe this is, in a coincidence of time and, occasionally, the location of the incident due to an accidental intact down in hundreds of millions of years after the time of an accidental and fortuitous location, in a number of accidental behavior, so that a distant world the way through the fossil show in front of people.

"环江翼龙"也许就是这样的，在一个偶然的时间、偶然的地点，因一次偶然的事件完整地保存了下来，又在亿万年之后的一个偶然的时间、偶然的地点，在几个偶然的行为中，让一个遥远的世界通过化石的方式展现在人们的面前。

The earth is not a mere fragment of dead history, stratum upon stratum like the leaves of a book, to be studied by geologists and antiquaries chiefly, but living poetry like the leaves of a tree,which precede flowers and fruit —— not a fossil earth, but a living earth; compared with whose great central life all animal and vegetable life is merely parasitic.

大地不只是已死的历史的一个片段，地层架地层像一本书的层层叠叠的书页，主要让地质学家和考古学家去研究；大地是活生生的诗歌，像一株树的树叶，它先于花朵，先于果实；——不是一个化石的地球，而是一个活生生的地球；和它一比较，一切动植物的生命都不过寄生在这个伟大的中心生命上。

The earliest and reliable Castanopsis fossil records date back at least to Eocene, and subfamily Castaneoideae fossil records found from Paleocene, it is indicated that appearance of Castanopsis is not later than Paleocene . All fossil records of Fagaceae and Castanopsis report from the Northern Hemisphere and their main distribution regions are in the Northern Hemisphere . It can be concluded that the Northern Hemisphere is the center of origin of Fagaceae and Castanopsis . However, owing to the discrepancy between fossil data and results of modern botany research as well as scarcity of fossil data from key area, precise center of origin of Castanopsis cannot be inferred.

栲属在地质历史上有着比现在广泛的分布，最早、最可靠的栲属化石记录发现于始新世地层，栗亚科化石在古新世就有发现，化石记录表明栲属起源的时间不晚于古新世，所有的壳斗科及栲属的化石都发现于北半球，现代分布也主要在北半球，壳斗科及栲属起源于北半球可以确认，由于化石证据与现代植物学的研究结果有较大差异以及关键地区化石证据的不足，具体的起源地尚不能肯定。

Supposes in 4,600,000,000 years perpetual flow in this, actually has had any, is already unable to recount; Only then from ancient stratum, discovery life process surviving vestige, but also might the testimony a wee bit remote past, such as: Early zoology and botany fossils and so on trilobita fossil, fish fossil, ferns, as well as after dinosaur fossil, fossils of bird, primitive time animal and human ancestor's fossil, but also had in the ancient times human history civilization corpse body with non-body vestige and so on, these vestiges nearly surmounted the entire Earth's life evolution history.

在这假定46亿年的长河中，究竟发生了什么，早已无法述说；只有从古老的地层中，发现的生命过程残存的遗迹，还可以见证一丁点儿的遥远过去，诸如：三叶虫化石、鱼化石、蕨类等早期动植物化石，以及之后的恐龙化石、鸟化石、原始时代动物及人类祖先的化石，还有古代人类历史文明中的尸体躯壳与非躯壳遗迹等等，这些遗迹几乎跨越了整个地球的生命演变史。

Professor Chris Stringer, from the Natural History Museum, London, UK, commented: If the the Neanderthal genome data show little evidence of potential hybridisation, that would fit with my view from the fossil evidence that, while interbreeding was probably possible, it may have occurred only rarely, with trivial impact on modern humans.

克理斯·Stringer教授，从自然历史博物馆，英国，伦敦，作注解：如果尼安德特人的基因组数据没有给出潜在的杂交的证据，那将从化石的证据适合我的观点那，当杂交繁殖是很可能可能的时候，它有可能只是很少发生，伴随着微不足道的对现代人类的影响。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
