WILL BAIRD of Dragon’s Tales posted Wednesday on the topic of dicynodonts, complete with artistic renditions. He mentions the last dicynodont fossil known showed up in the early Cretaceous, and speculates some might have survived to the end of the Cretaceous. Too bad they couldn’t make it to the present day! Since these creatures were a branch on the line to mammalian evolution, retain features of our therapsid ancestors, and are long extinct I think there are a lot of paleontologists and evolutionary biologists out there who would sacrifice various body parts if it would enable us to find a living example. I’m not even a paleontologist and I’d consider giving up a little toe.

The dicynodonts were our cousins, not ancestors. They were part of Anomodontia:

Just goes to show that haste makes sloppy taxonomy. Edited for clarity.

Will,
the Anomodontia were closer to the therocephalians (and the cynodonts) than the gorgonopsians?
I always thought it was the other way around; Therocephalia, Gorgonopsia and Cynodontia form a common clade Theriodontia, with Anomodontia as an outgroup:
