Probelesodon is an extinct genus of chiniquodontid cynodont. Fossils have been found from Argentina and Brazil of Triassic age. Specimens were first discovered from the Chañares Formation in La Rioja Provence, Argentina that date back to the Anisian stage of the early Middle Triassic. A new species, P. sanjuanensis, was named in 1996 on the basis of a skull found from the Ischigualasto Formation. This extends the temporal range of Probelesodon into the Carnian stage of the Late Triassic.
