41VV0218 LV2 BISONMANDIBLES SFM FINAL

This SfM model is one of a three part glimpse into archaeology and the process of excavation from Bonfire Shelter in the Lower Pecos region of Texas. Bonfire Shelter is the earliest and southernmost Native bison jump in North America. This mass of bone to the left and underneath the large boulder is a grouping of Bison antiquis (extinct bison) bones and mandibles (lower jaw). The large boulder in the model might have been used by humans as an anvil to break open the bison longbones for marrow extraction. The SfM model following this one shows the excavation starting from the sediment deposit above, down to this level.

本结构从运动（Structure from Motion，SfM）模型是德克萨斯州下佩科斯地区篝火庇护所考古研究与发掘流程三部曲之一。篝火庇护所是北美地区已知最早、最南端的原生野牛跳崖遗址。模型左侧巨型石块下方的骨堆，为已灭绝的古野牛（Bison antiquis）骨骼与下颌骨（lower jaw）的集合遗存。模型中的这块巨型石块，可能曾被人类用作砧石，用以敲开野牛长骨以获取骨髓。紧随本模型发布的另一部SfM模型，展示了从上方沉积层向下发掘至该层位的考古过程。数据来源：Objaverse 1.0 / Sketchfab
