Fabanychus (lit.'bean claw') is an extinct genus of drepanosauromorph reptiles known from the Late Triassic (Norian age) of the United States. The genus contains a single species, Fabanychus monos, known from several isolated hand claws found in outcrops assigned to the Revueltian teilzone in the Chinle Formation of Arizona and Cooper Canyon Formation of Texas. The shape and curvature of the claws of Fabanychus are similar to those of the contemporary drepanosauromorph Ancistronychus, and indicate it likely had a fossorial ecology, meaning it was well-adapted to digging.
