The Fossil Cabin near Medicine Bow, Wyoming, United States, was built in 1932 as a roadside attraction.

Boylan had come from California to homestead in Wyoming and had been collecting bones for seventeen years, intending to create sculptures of dinosaurs in front of his house and gas station along the Lincoln Highway.

Boylan filed for a homestead near Como Bluff in 1908, where extensive deposits of fossilized dinosaur bones had been discovered in the 1870s.

Initially intending to erect a complete skeleton, Boylan was daunted by the task, as well as the likelihood that few of the bones came from the same animal, or even the same species.

Operated by his widow, Grace, the gas station continued until the 1960s, when the construction of Interstate 80 caused a fall-off in traffic on Route 30.
