Although some parts of the Ruhuhu Formation probably correlate with the \u003ci\u003eEodicynodon\u003c/i\u003e or \u003ci\u003eTapinocephalus\u003c/i\u003e assemblage zones of the South African Karoo Basin, it is uncertain whether \u003ci\u003eE. tolani\u003c/i\u003e is older than \u003ci\u003eE. bathystoma\u003c/i\u003e or \u003ci\u003eE. mahalanobisi\u003c/i\u003e. There is less evidence for extensive anteroposterior translation of the mandible in \u003ci\u003eE. tolani\u003c/i\u003e than in other dicynodonts. The jaw joint is specialized for allowing some medial-lateral motion. Mastication involved unilateral chewing. Flexure of the postdentary bones relative to the fused dentaries permitted the posterolaterally directed rows of teeth on one side of the skull and mandible to move past one another. The long tooth rows and prominent horn-covered ridges and grooves on the palate and mandible of \u003ci\u003eEndothiodon\u003c/i\u003e are unique among dicynodonts. Comparisons with other taxa suggest that its feeding system may have been specialized for cutting three-dimensional objects such as stems or rhizomes. The dicynodont feeding system is very stereotyped throughout the clade's history, but \u003ci\u003eEndothiodon\u003c/i\u003e escaped the constraints that affected other dicynodonts, allowing it to evolve a unique skull morphology. This evolutionary flexibility did not translate into high taxonomic richness (we recognize only three species of \u003ci\u003eEndothiodon\u003c/i\u003e), but \u003ci\u003eEndothiodon\u003c/i\u003e was able to achieve high levels of relative abundance in some basins.http://zoobank.org/urn:lsid:zoobank.org:pub:9686F708-2E6E-40EB-956F-05659889684FSUPPLEMENTAL DATA—Supplemental materials are available
