Rhynchippus is an extinct genus of notoungulate mammal.
Rhynchippus was about 1 metre (3.3 ft) in length and weighted up to 120 kg, with a deep body and three clawed toes on each foot. Although its teeth were extremely similar to those of horses or rhinos, Rhynchippus was actually a relative of Toxodon, having developed teeth suitable for grazing through convergent evolution. Unlike its relatives, Rhynchippus had no large tusks; they were the same size and shape as the incisors. Enamel on the molars allowed it to chew tough food.
