化石的

In his more than half a century' s scientific and educational career, Professor Yang made significant contributions to Chinese geology and paleontology, especially in the fields of fossil brachiopods, Carboniferous biostratigraphy, paleobio-geography, and paleoecology.

杨式溥对中国西北和西南地区石炭纪的腕足动物化石的研究为中国石炭纪地层的内部界线划分、对比、化石组合、地理区系及沉积类型提供了重要证据。

The average δ〓O value of brachiopod shells from Givetian in Longmenshan area is comparable with those of the same geologic time from North America and Australia. The three continents were in the same latitudes although the Australia was in the south hemisphere, hence the annual average temperatures.

5龙门山地区中泥盆世腕足化石的δ〓O与同时期北美和澳大利亚腕足化石的δ〓O值非常接近，它们当时都是地处低纬度地区，海水年平均温度相同，因此三个地区海洋的δ〓O值也应相同。

One interpretation regarding the absence of fossils during this important 100-million-year period is that early animals were soft bodied and simply did not fossilize.

构造活动期，生物组合具有低分异度、低丰富度的特点，化石的纹饰结构也相对简单；构造平稳期，湖生生物迅速发展并繁盛，生物组合具有高分异度、高丰富度的特点，化石壳面纹饰结构趋于复杂化、多样化。

In condensed sections, fossils and organic, phosphatic and glauconitic material tend to be concentrated compared with rapidly deposited sections that contain few fossils.
