The reintroduction of Equus caballus (horse) into North America during European-American contact altered Native American life on the Plains. The horse influenced a variety of cultural practices, including transportation and warfare. Despite the impact of the horse on Native Plains cultures, there is a paucity of horse remains in the archaeological record in Wyoming and the Great Plains in general. In this article, the results of a reanalysis of a set of horse remains from the Protohistoric Period are described. The horse remains from the Blacks Fork River site in Wyoming provides a unique opportunity to examine a preserved interaction between humans and a horse from the early contact period. Reanalysis includes a re-examining of the faunal elements to re-establish the horse's age and evidence of butchering and radiocarbon dating to confirm the temporal span of the remains.

马球的重新引入美国人与欧洲人接触期间进入北美，改变了美国原住民在平原上的生活。这匹马影响了各种文化习俗，包括运输和战争。尽管马匹对土著平原文化产生了影响，但在怀俄明州和大平原地区的考古记录中，仍然很少有马匹遗骸。在本文中，描述了重新分析原始史时期的一组马遗骸的结果。来自怀俄明州布莱克斯福克河遗址的那匹马遗骸为检查人与马之间早期接触后保存的相互作用提供了独特的机会。重新分析包括重新检查动物成分以重新确定马的年龄以及屠夫和放射性碳测年的证据，以确认遗骸的时间跨度。
