Chelomophrynus is an extinct genus of prehistoric anurans in the family Rhinophrynidae.

[1][2] A single species is known, Chelomophrynus bayi from the Uintan Wagon Bed Formation of Wyoming.

[1] 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.
