本文描述了1987年建立的一个实验，以研究动物骨骼的分解，主要是从较小的物种，在一个积累的有机垃圾堆。该项目是作者对主要是较小动物骨骼的降解进行的更广泛的比较研究的一部分（Nicholson，1991，1992，1993，1996a），目的是模拟埋藏过程，并提供数据，以提高我们对考古遗址骨骼保存的理解。经过7年的积累国内堆肥堆掩埋，一套哺乳动物，鸟类和鱼类的骨骼被挖掘出来，并检查形态，组织学和化学修饰的证据。通过与大约在同一时间埋葬和挖掘的类似骨骼套件相比，堆肥堆中的大多数骨骼都保存得很好。有人认为，这可能是一个结果的交联胶原与腐殖酸从土壤中，导致在结构耐酶攻击。
This paper describes an experiment set up in 1987 to investigate the decomposition of animal bones, mainly from smaller species, within an accumulating dump of organic refuse. The project forms part of a wider comparative study by the author into the degradation of mainly smaller animal bones (Nicholson, 1991, 1992, 1993, 1996a) with the aim of modelling taphonomic processes and providing data to enhance our understanding of bone preservation on archaeological sites. Following 7 years of burial within an accumulating domestic compost heap, a suite of mammal, bird and fish skeletons was excavated and examined for evidence of morphological, histological and chemical modification. By comparison with similar suites of bones buried and excavated at around the same time, most of the bones from the compost heap were very well preserved. It is argued that this may be a consequence of the cross-linking of collagen with humics from the soil, resulting in a structure resistant to enzymatic attack.
