Cruschedula is an enigmatic bird genus considered to be nomen dubium which consists of the single species Cruschedula revola.

The bone was found in beds of the Deseado Formation near San Jorge Gulf in Southern Patagonia. Designated the holotype specimen it was added to the Bernardino Rivadavia Natural Sciences Museum a
