Results of X-ray fluorescence analyses of major elements for concretions, whale bones, calcite vein, and matrix , and Carbon and oxygen stable isotope ratios for the studied samples in Unosaki coast, Oga peninsula, Japan.

Table S1. Results of X-ray fluorescence analyses of major elements for concretions (con.), whale bones (bone), calcite vein, and matrix (wt.%). Samples of concretions and whale bone were collected from concretions 23 and 47 of Watanabe et al. (2017). LOI: loss of ignition. The low total values could be due to insufficient heating of the carbonate.

Table S2. Carbon and oxygen stable isotope ratios for the studied samples.
