提出了一种基于骨骼组合中不同完整关节的相对数量来确定脊椎动物骨骼的离断序列的统计技术。对于肯尼亚北部图尔卡纳湖边缘的现代托皮（Damaliscus korrigum）遗迹来说，断节模式非常一致。在旱地上的这一顺序与报道的在有水的情况下脱节的牛科动物的顺序不同。在陆地上，首先以单块形式释放的骨头是那些最不容易被流动水流移动的骨头。最后发布的是那些最容易移动的。开发了一种随机散射模型，该模型表明，在骨头浓度高的情况下，分散率很大，并且随着骨头之间距离的增加而迅速降低。这导致散射有效停止的情况。或多或少稳定分散的区域仅取决于每个随机事件移动骨骼的平均距离。铰接单元本身不太可能参与分散；分散似乎发生在整个脱节过程中。
A statistical technique for determining the disarticulation sequence of vertebrate skeletons based on the relative numbers of different intact joints in an assemblage of bones is presented. For remains of modern topi (Damaliscus korrigum) on the margin of Lake Turkana, northern Kenya, the disarticulation pattern is very consistent. This sequence, on dry land, differs from that reported for bovids that have disarticulated in the presence of water. On land the bones first released as single bones are those moved least easily by currents of moving water. The last released are those moved most easily. A model of random scattering was developed that suggests that the rate of dispersion is great at high concentrations of bones and decreases rapidly as the distance between bones increases. This leads to a condition where scattering effectively stops. The area of more or less stabilized dispersion is dependent only on the mean distance that each random event moves a bone. It is unlikely that articulated units themselves are much involved in scattering; scattering appears to take place throughout the course of disarticulation.
