虽然对考古遗址中贝类的季节性进行了许多研究，但尚未获得一种了解毛纹Ostrea edulis死亡季节的技术。方法是通过从不同地点和环境中收集的大型现代对照样品的薄切片外壳来实现的。发现年际线形成于3月和4月。测量增量不是解释死亡月份的可行技术，因此注意到微观结构的季节性变化。进行盲测，结果显示91%的评估正确率为±1个月。一名学生进行的第二次盲测表明，这项技术是可以学习的，但需要投入大量时间。
Abstract Although there have been many seasonality studies of shellfish from archaeological sites, a technique for understanding season of death for Ostrea edulis has never been attained. A methodology was achieved through thin sectioning shells from a large modern control sample collected from different locations and environments. It was found that annual lines were formed in March and April. Measuring increments was not a feasible technique for interpreting month of death so seasonal changes in the microstructure were noted instead. A blind test was carried out showing that overall 91% of assessments were correct±1 month. A second blind test by a student showed the technique may be learnt but that a large time investment is needed.
