The purpose of this study is to find the new technique of paleontological observation using the tunable light source. Our materials for this observation axe some kinds of fossils, such as sea urchin, starfish, bivalves, plants, traces of organisms and so on, containing some of present organisms. We observed the reflection and absorption or luminescence from the materials with the different narrow bands of light in the 254 nm, UV, 365 nm, 417 nm, 470 nm, 505 nm, 530 nm, 590 nm, 820 nm and etc. We found out that the calcareous materials axe especially illuminated with the light of 530 nm and the materials which have tuffaceous matrix, plant fossils and trace fossils, are depicted clearly with the infrared light. We thought that the observation by different wavelengths is very available to get tare new another data for paleontology. In future, we will try to the chemical analysis of the part that generates fluorescence and will make the chart of color of luminescence of standard wavelengths

本研究的目的是探索利用可调谐光源进行古生物观察的新技术。我们这次观测的材料是一些种类的化石，如海胆、海星、双壳类、植物、生物遗迹等，其中包含了一些现代生物。我们观察了材料在254 nm、UV、365 nm、417 nm、470 nm、505 nm、530 nm、590 nm、820 nm等不同窄带光下的反射、吸收或发光，发现钙质材料特别受530 nm光的照射，植物化石和遗迹化石，都能用红外光清晰地描绘出来。我们认为，不同波长的观测是非常有效的，可以为古生物学的研究提供新的资料。今后，我们将尝试对产生荧光的部分进行化学分析，并制作标准波长的发光颜色图
