In the middle of nowhere Western Kansas off of US Highway 83 is the Keystone Gallery, a little gem of a museum and art gallery that sits in an old church between the towns of Oakley and Scott City. There are numerous fossils of sea creatures & monsters that used to dwell in this area of western Kansas 82 to 87 million years ago. The owner is the son of a famous paleontologist (Marion Charles Bonner) whose fossils can be found in museums all over the country. Inside you can see a 20 foot long mosasaur, a 14-foot Xiphactinus fish, Pteranodon specimens, birds, and more!

The art and fossil gallery is very nearby to Monument Rocks (Kansas's first National Natural Landmark), Little Jerusalem, and El Cuartelejo (Kansas only Indian Pueblo).
