A paper for which Assistant Professor Hironao Matsumoto served as the lead author has been published in Science.

This paper summarizes the results of reconstructing the osmium isotope ratio in seawater throughout the Cretaceous period (143–66 million years ago).

This study is expected to further advance our understanding of past large-scale volcanic activity and changes in continental weathering patterns.
