More than 900 vertebrate bones, ranging from Late Pleistocene to Holocene in age, have been identified in a collection that was recovered by a single dredging operation for the construction of artificial lakes near Lent (Nijmegen, province of Gelderland, the Netherlands). The Late Pleistocene assemblage comprises mainly Weichselian glacial fauna such as mammoths, reindeer and bison. Some Eemian fauna is represented as well, e.g. straight-tusked elephant. The abundance of certain species over others suggests that preservation bias had a considerable impact on this assemblage, while its time-averaged nature resulted in overrepresentation of certain species. A case study is here conducted on a fragmentary skull of a subadult woolly mammoth bull with embedded blowfly puparia. Some of these puparia are fully developed, indicating prolonged exposure of the mammoth carcass.

荷兰海尔德兰省 Lent 疏浚现场晚更新世巨型动物和蛹的分析

超过 900 块脊椎动物骨骼的年龄范围从晚更新世到全新世，这些骨骼是通过一次疏浚作业回收的，用于在 Lent（荷兰海尔德兰省奈梅亨）建造人工湖。晚更新世组合主要包括魏克瑟尔冰川动物群，如猛犸象、驯鹿和野牛。一些埃米亚动物群也有代表，例如直牙大象。某些物种相对于其他物种的丰度表明，保存偏差对该组合产生了相当大的影响，而其时间平均性质导致​​某些物种的代表性过高。一个案例研究是在一个亚成体猛犸象的头骨上进行的，该头骨内嵌有飞蝇蛹。其中一些蛹已经完全发育，
