Domebo Canyon, Oklahoma is a Paleo-Indian archaeological site: the site of a mammoth kill in the prairie of southwestern Oklahoma. The Domebo archaeological site features deposits of both incomplete and partially articulated mammoth skeletal remains. Also found at the site were two complete and one fragmentary projectile point, along with three un-worked tool flakes made by prehistoric hunters who lived during the Pleistocene Epoch. The site is historically significant because it marks one of the few archaeological sites in which mammoth skeletal remains were discovered in situ along with prehistoric stone tools. The site gives insight into the lives of prehistoric hunters and their impacts, helping the archaeological understanding of subsistence strategies during the Pleistocene Epoch. Radiocarbon dates of ca. 11,000 BP were recorded for the lower area of the Domebo Formation where the remains were discovered. This area where the mammoth was killed is thought to have once been a stream with abundant vegetation. Fossils of both freshwater and land mollusks further support this conclusion. The climate during this time would have supported these mollusks.
