Keystone Gallery is one of the only native stone buildings remaining in Southeast Logan County. The limestone building blocks were quarried nearby and the sand for mortar hauled by oxen team from the Smoky Hill River in 1916.

Established in 1991, the gallery is dedicated to preserving local Niobrara fossils from the surrounding “Badlands of Kansas”. The gallery also works with museums throughout the United States and other countries on various scientific projects. The Bonner family started fossil hunting in 1925, and museums throughout the world now house their specimens. Research continues to be an on-going process.

In 2010, the Bonner family was honored by having a new fish genus named for them. The fossil, now called Bonnerichthys gladius, was the largest fish of the Kansas Niobrara Sea. It was a huge filter feeder, much like a present day basking shark, that reached lengths of over twenty feet. The specimen was found by Chuck Bonner in 1971.

Keystone Gallery Museum has excellent examples of Niobrara Cretaceous fossils found by Chuck Bonner and Barbara Shelton including numerous fossil fish, mosasaurs, pteranodons, birds, turtles and invertebrates. Over thirty four permanent fossils are on display and temporary exhibits are rotated on a timely basis.

The gallery‘s gift shop features Bonner‘s paintings and Shelton‘s photography. Gift shop inventory includes fossils and minerals from the United States and around the world, plus Monument Rocks souvenirs, fossils and artwork. This is the only rock and mineral shop located in Western Kansas.
Chuck Bonner has completed many museum murals and also offers fossil lectures on a fee basis. He has lectured at Yale-Peabody Museum, Cincinnati Science Center and other prestigious institutions.

The gallery has been featured in many national TV, newspaper and magazine publications including KC to Kanorado, KCPT Public, Hatteberg‘s People, books including 10,000 Places to See Before You Die, Planet Ocean, Crusin‘ the Fossil Freeway, The Kansas Guidebook, (by Marci Penner), Kansas Magazine!, Kansas Curiosities, Kansas Travel and Tourism (created Ready Made Adventure) video and brochure (called Discovering Dinosaurs & Sea Monsters).

Shelton and Bonner sponsored the Monument Rocks site in the competition for the first “8 Wonders of Kansas” project by the Kansas Sampler Foundation. In 2008, the gallery received recognition from Governor Sebelius and the Sampler Foundation as one of the awardees.
