For five years starting in 2016, the National Museum of Nature and Science conducted an interdisciplinary comprehensive research project titled "Analysis of Earth and Life History Based on Chemostratigraphy and Dating." In this research, we mainly used three mass spectrometers to analyze the isotope ratios of oxygen, carbon, strontium, etc. contained in rocks and sediments, and to clarify the ages of strata and the environment during deposition. , we were able to determine in detail the timing of emergence and extinction of ambiguous fossil species. This exhibition introduces some of these research results.
