Shoshonia is a Devonian-era extinct genus of prehistoric sarcopterygians, or lobe-finned fish. It contains one species, Shoshonia arctopteryx.[1] The fish was named in reference to the Shoshoni people and the Shoshone National Forest in Wyoming, in the United States.[2]

The fish was described from a fossilized pectoral fin endoskeleton and shoulder bones found in Wyoming.[3] Based on skeletal morphology, the fish are believed to have been ancestors of the coelacanths. Notably, the fins were asymmetric.[4]
