Histologic examination of rehydrated tissue samples from late Pleistocene (Alaskan) mammal mummies demonstrates that the preservative effect of freezing and drying extends to remains 15,000 to 25,000 years old. Some muscle and liver tissue retained identifiable histologic structures. Most tissues were completely disintegrated and partly replaced by masses of bacteria, an indication of considerable postmortem decay before the remains were entombed beneath the permafrost zone.
对更新世晚期（阿拉斯加）哺乳动物木乃伊的复水组织样本进行的组织学检查表明，冷冻和干燥的防腐效果可延伸至15000至25000年前的遗骸。一些肌肉和肝脏组织保留了可识别的组织结构。大多数组织已完全分解，并部分被大量细菌取代，这表明在遗骸被埋入永久冻土带之前，已经发生了相当程度的死后腐烂。
