Museums hold 2,354 specimens collected within 10 miles of Gypsum between 1865 and 1975: 1,772 Animalia, 514 Plantae, 63 Fungi, 4 Chromista, 1 Unrecorded. 12 distinct Species records are shown. Collected by A. D. Selby, A. F. Satterthwait, A. J. Eames and others. Each is a physical object with a catalogue number, and each entry opens the museum's record. This is what was collected and kept, not a survey of what lives here - nothing can be concluded from a species being absent.
