          <datacite:description descriptionType="Abstract">竜骨ノジュールの炭酸塩の炭素同位体比，酸素同位体比および炭酸塩骨格内硫酸イオンの硫黄同位体比を分析した結果，竜骨周辺には酸化的環境が存在し，竜骨のごく近傍が有機物分解により還元的になってノジュールが形成されたことが明らかになった．またノジュール形成の漸進的過程が炭素・酸素同位体比から明瞭に解読できた．このような成因を考察した結果，竜骨ノジュールを用いて海底古水温の推定を行う場合には，切片等を用いてノジュールを詳細に観察した上で，竜骨に最も近い場所（骨の内部空隙の内側の骨と接する場所）に最初に晶出する方解石を用いることが好ましいことが分かった．</datacite:description>
          <datacite:description descriptionType="Abstract">Stable isotope analyses of carbonate carbon and oxygen, and carbonate-associated sulfate on reptile-bone nodules indicated that the reptile corpse had been surrounded by oxic water but it became anoxic because of the organic decomposition resulting calcareous nodule formation. The stable isotope results also showed progressive process of nodule formation. Interpretation of the isotope data and visual observation of the nodule demonstrated that the calcium carbonate precipitated closest to bone (calcium carbonate attached on the bone in vacant space inside of a bone) is most recommended material for paleothermometry.</datacite:description>
