And considering the extremely imperfect nature of the fossil record , chances are that this figure significantly underrepresents the number of apes that actually existed at that time 由于化石记录必然是断烂朝报,这个数字很可能根本不能反映实情。
Scientists have long believed that bees first appeared about 120 million years ago - - but previous bee fossil records dated back only about 65 million years 科学家们已经相信蜜蜂最早出现于1亿2千万年已经很久了,但是以前发现的蜜蜂化石记录只是在6500万年前。
While many creationists hold this view for some smaller aspects of creation , for example the existence of the fossil record , the argument has been largely superceded 虽然许多创造学家为一些造物的更小形象持有这个看法,例如存在的化石记录,很大程度上取代了辩论。
Both of these facts mean it is likely that some lineages which seem to make their first appearance in the extratropical fossil record actually started out near the equator 上述两种因素都表明某些世系虽最早出现在热带外区域的化石记录上,实际上却有可能起源于赤道附近。
In the past 15 years new opportunities to study the region ' s rock and fossil records have finally enabled investigators to piece together a more complete picture of amazonian history 过去15年来,由于有新的机会研究该地区岩石及化石记录,终于使研究人员得以拼凑出更完整的亚马逊河历史全貌。

All these fossil fruits and seeds are reported for the first time in china , and corylopsis , liriodendron , nyssa , sabia and symplocos are new additions to the chinese megafossil plants 所有这些果实和种子的化石在中国均为首次报道,其中蜡瓣花属、鹅掌楸属、蓝果树属、清风藤属和山矾属还是该属在中国的首次大化石记录。
If we could document the spontaneous generation of just one complex life - form from inanimate matter , then at least a few creatures seen in the fossil record might have originated this way 要是复杂生物可以从没有生命的物质自然发生,我们只要提出证据,哪怕只是一件,那麽我们就可以推论,化石记录上至少有一些生物也许就是以同样的方式形成的。
As he also correctly points out , many important changes took place in our ancestors during the whole span of four million or so years for which we have a fossil record , while relatively few have taken place recently 他也很正确地指出来,在我们有一项化石记录的这400万年左右的整个时间间隔内,我们的祖先曾经经历很多重要的改13 . 1变,而相对地说近来这种事情就没怎么发生了。
In 1982 they recognized that the typical approach for defining the last occurrence of a given species did not take into account the incompleteness of the fossil record or the biases introduced in the way the fossils were collected 他们在1982年指出,过去用来定义某个物种在生命史上最后一次出现的方法,没有考虑到化石记录不完整,或者化石收集不是个随机过程等事实。
