Chelomophrynus is an extinct genus of anurans in the family Rhinophrynidae. A single species is known, Chelomophrynus bayi from the Uintan Wagon Bed Formation of Wyoming. It was probably a subterranean feeder, like the modern member of the family, Rhinophrynus dorsalis. As most burrowing anurans, it likely used its hind feet for digging, thereby entering ground backwards.
