The holotype fossil is in the collection of the Smithsonian's National Museum of Natural History.

It was collected from the Fossil Butte Member, Green River Formation, Lincoln County, Wyoming.

The species name cercanaxius comes from ancient Greek words kerkion, tail, and anaxios, worthless, in reference to the rudimentary pygostyle of this species.
