Research conducted by Debra Jennings back in 2006, determined that the bones were accumulated in the past when the site was part of a shallow alkaline lake.

During the winter, the excavation sites are closed to visitors, but over the summer months (late-May to mid-September) active digging occurs every day (weather permitting).

The replica skeleton on display is 106 feet long and is the first mount based on data from the second and most complete Supersaurus ever found affectionately named "Jimbo" (WDC DMJ-001) which was donated to the museum in 2003.

One of the newest members to the museum is the almost 90% complete, composite skeleton of a Camarasaurus found on the property by staff and visitors, excavated over the past 20 years.

From these times before and after the dinosaurs, the museum hosts an impressive display of pre-Mesozoic fossils, including numerous Devonian fish and invertebrates.

The museum also houses a fully functional preparation lab, where staff and visitors can be seen cleaning, repairing and preserving fossils found on the property as well as from other locations around the country, all year long.
