Temporal assignments carry substantive weight, and archaeologists regularly assume that artefacts from discrete temporal units may differ in ways that convey changes in preference or behaviour. Similarly, archaeologists regularly assume that raw material differences articulate with stone tool morphology, and the role of differential raw material quality and preference associated with Caddo lithic technology remains largely unexplored. Whether a particular artefact is found in or outside of burial contexts is a sensitive and regularly discussed topic in the archaeological literature, providing valuable insights related to prehistoric burial practices, as well as generational shifts in aesthetics, design, and raw material preferences. These assumptions were tested using geometric morphometrics, yielding results in support of the hypothesis that Perdiz arrow point shape is protean, and that significant differences existed in shape by time, raw material, and burial context.

时间分配具有实质性的重要性，考古学家通常假设来自离散时间单位的人工制品在传达偏好或行为变化的方式上可能有所不同。同样，考古学家通常认为原材料差异与石材工具的形态有关，而原材料差异质量和与Caddo石器技术相关的偏好的作用在很大程度上仍未得到开发。无论是在墓葬环境中还是在墓葬环境之外发现特定的人工制品，都是考古文献中一个敏感且经常讨论的话题，它提供了与史前墓葬实践以及美学，设计和原材料偏好的世代转变有关的宝贵见解。这些假设已使用几何形态计量学进行了测试，
