1·The ichnofacies is the grouping of characteristic trace fossil association tending to rscirrence through a rather long interval of geologic time, and their environmental implication.

遗迹相是指一组具有特征的遗迹化石组合，在一段相当长的地质时期中不断的重视以及它们的环境意义。

2·The fossil dinosaur eggs included 19 species assinged to 10 genera belonged 7 families. They are assosiated with Hadrosaurs, Tyrannosaurs, Sauropods, Charophytes, Sporopollen and trace fossils et al.

3·Dr. Tattersall believes the leap to humans may have been brought about very suddenly, perhaps by a few critical genetic changes, which is why the transition is so hard to trace in the fossil record.

塔特萨尔博士认为，转变到人类的飞跃产生已经很突然，或许由于几个重要的基因变化。 这就是为什么这个转变在化石记录里很难找到。

4·Birds evolved from dinosaurs, but the origin of their feathers may trace back even deeper in time, to the common ancestor of dinosaurs and pterosaurs, like the fossil at left.

5·The myth is based on fossil evidence, but these days genetics can trace the path of evolution, too.

传说来源于化石,但是最近有研究表明通过遗传学的深入研究同样能够让我们追溯到物种进化的整个过程.

6·In this study, 1003 core samples were collected, found 557 fossils of ostracods, identified the 15 fossil assemblage, the measured carbon and oxygen isotopes 252, and 189 trace element ratio data.

本研究共采集岩心样品1003个，发现介形类化石557个，鉴定出15个化石组合带，测得252组碳氧同位素和189组微量元素比值数据。

7·You may wonder how the expert on fossil remains is able to trace descent through teeth, which seem specious pegs upon which to hang whole ancestries.

你也许会感到疑惑遗留的化石专家怎么可能通过看似华而不实的借口的牙齿来追踪后裔呢？而这些借口却又是整个家族的荣誉所在。

8·However, there are some flaws in the current laws which can't attacks availably the infringement on ammonite rest fossil and the transgression of the geologic trace.

但是目前我国保护古生物化石与地质遗迹的法律存在严重缺陷，不能有效地打击侵害古生物化石与地质遗迹的违法犯罪行为。

9·Article 2 the term fossil as mentioned in the present Measures refer to the remnant or trace of an animal or a plant of a past geologic age embedded and preserved in the earth's crust.

第二条本办法所称古生物化石，是指地质时期形成并赋存于地层中的动物、植物等遗体化石或者遗迹化石。
