与桡足类动物的外骨骼或正常卵囊相比，Diaptomus castor的卵囊异常坚固，可以在第四纪沉积记录中保存下来。在丹麦和格陵兰岛的冰川晚期和冰川后湖泊沉积物中发现了Diaptomus c.c oror的卵囊。桡足类化石卵囊的鉴定具有重要意义，因为桡足类是淡水水体中非常重要的无脊椎动物类群；但这一群体很少在湖泊沉积物中发现。
In contrast to the exoskeleton or normal egg sacs of copepods, egg sacs with resting eggs of Diaptomus castor are exceptionally robust and can be preserved in the Quaternary sedimentary record. Egg sacs referred to Diaptomus cf. castor have been recovered from Late-and Postglacial lake sediments in Denmark and Greenland. The identification of fossil copepod egg sacs is important, since Copepoda is a very important group of invertebrate animals in freshwater bodies; but a group that is rarely reported from lake sediments.
