Development of experimental method for understanding fossilization

化石是指在地质时代从活的动植物到化石的过程，是欣赏化石的关键。这项研究开发了一种实验方法来理解这种石化现象，使用了活的和化石的介形类，小型甲壳类动物。首先，通过对活体介形类的观察，了解介形类的有机结构和生态。通过观察水族箱底部沉积的人类遗骸，可以追踪到变化和损失。最后将这些化石与地层中的介形类化石进行了比较。

Fossilization that means the process from living animals and plants to fossil ones in geologic time is essential for appreciating fossils. An experimental method for understanding the fossilization was developed in this study, using living and fossil ostracods, small crustacean. At first, organic structure and ecology of ostracoda are understood through observation of living ones. Alterations and losses are traceable by observing deposited mortal remains on the bottom of aquarium. At last, these remains are compared with fossil ostracods from strata.
