The Lost Burro Formation is a Middle to Upper/Late Devonian geologic formation in the Mojave Desert of California, in the Western United States.
The Dolomite formation is exposed in sections of the Darwin Hills, Santa Rosa Hills, Talc City Hills, Inyo Mountains near the Cerro Gordo Mines, Panamint Range near Towne Pass, and the Argus Range.
Outcrops of the formation in Death Valley National Park have produced fossils of the placoderm Dunkleosteus terrelli, a small cladodont shark, the crushing tooth of a cochliodont, and the pteraspidid Blieckaspis priscillae.
