Waco Mammoth Dig Shelter, Paleontological dig shelter in Waco, United States.

Waco Mammoth Dig Shelter is a large covered facility that protects fossils from an ancient Ice Age site. An elevated walkway lets visitors view the bones up close while walking through the preserved excavation area.

In 1978 two men searching for fossil shells along a tributary of the Bosque River found a mammoth femur; Baylor University and other researchers then excavated the site. The bones belong to a nursery herd of Columbian mammoths, mostly female and young, buried in a single mudflow about 65,000 years ago. A second bone bed holds a bull mammoth and a camel.

The site is part of Waco Mammoth National Monument, proclaimed in 2015 and run with the City of Waco and Baylor University. Exhibits explain the 1978 discovery by two amateur fossil hunters and the work of Baylor paleontologists, and rangers lead programs on the Columbian mammoths.

Visitors must join guided tours that depart from the Welcome Center to enter the covered excavation area. The facility is climate-controlled and offers seating, restrooms, and basic amenities throughout the site.

The site holds the remains of a herd of young mammoths that died approximately 65,000 years ago. This grouping of fossils shows a rare example of how these animals lived and perished together.
