A method of reconstruction of outer sublittoral relative depth using ostracods has been suggested. The new method is based on an increasing percentage of ostracods with distinct eye tubercle with water depth rising. The proposed method was developed and checked on late Barremian–Aptian ostracods of the Crimea; the results are similar to those obtained from oxygen isotope analysis and principal component analyses. The combined curve of the depth changing in the Crimean sea during late Barremian–Aptian aligns with the global eustatic curve.

海洋龙骨相对深度重建方法:来自克里米亚山脉上巴里米亚-阿普提安的案例研究

有人提出了一种利用兽脚类动物重建近海滨下相对深度的方法。这种新方法是基于随着水深的增加,具有明显眼结节的兽脚类动物的百分比增加。拟议的方法已开发并在克里米亚的晚期巴雷米亚-Aptian兽足上进行了检验。结果类似于通过氧同位素分析和主成分分析获得的结果。Barremian-Aptian晚期克里米亚海中深度变化的组合曲线与全球欣快曲线一致。
