Response of life history traits of modern and Cretaceous mollusks to the present and past marine environment has been investigated by means of sclerochronological and geochemical analyses. As a result, modern bivalves living in northwestern Pacific cold water environments have a long life span and preserve a long-term environmental record in their internal shell increments. Stable oxygen isotopic analysis of well-preserved planktonic and benthic foraminiferal tests and bivalve shells from the Upper Cretaceous of the North American mid-continent reveals slightly colder sea surface and bottom temperatures for the Western Interior Seaways and Northwest Atlantic continental shelf during the Late Cretaceous than those during the mid-Cretaceous. Also, this study demonstrates that Late Cretaceous bivalves from these marine realms had life history traits that were similar to those of modern bivalves from a lower latitude warm marine environment.

通过年代学和地球化学分析，探讨了现代和白垩纪软体动物生活史特征对现代和过去海洋环境的响应。因此，生活在西北太平洋冷水环境中的现代双壳类具有很长的寿命，并在其内部壳增量中保存了长期的环境记录。上白垩统保存完好的底栖有孔虫化石和双壳类贝壳的稳定氧同位素分析 北美中部大陆的白垩纪显示，晚白垩纪西部内陆水道和西北大西洋大陆架的海面和海底温度比白垩纪中期略冷。此外，这项研究表明，晚白垩世双壳类从这些海洋领域的生活史特征，是类似的现代双壳类从低纬度温暖的海洋环境。
