The Waco Mammoth National Monument is a paleontological site and museum in Waco, Texas, United States where fossils of 24 Columbian mammoths (Mammuthus columbi) and other mammals from the Pleistocene Epoch have been uncovered. The site is the largest known concentration of mammoths dying from a (possibly) reoccurring event, which is believed to have been a flash flood. The mammoths on site did not all die at the same time but rather during three separate events in the same area. A local partnership developed around the site after the initial bone was discovered. The Waco Mammoth Foundation worked in partnership with the city of Waco and Baylor University to develop the site. Baylor's involvement mainly included the research, preservation, and storage of materials from the site, while the city of Waco contributed to the protection of the land.[3] In 2015, they successfully sought the National Monument designation to bring the expertise of the National Park Service into the partnership
