This paper describes a specimen of Thrinaxodon liorhinus, evidently a mature female, with a very tiny specimen closely associated with it in the same nodule. Attention is largely
given to tooth replacement. The conclusion arrived at is that Thrinaxodon has not yet
reached that stage in evolution where light is thrown on the development of the typical
mammalian arrangement of dental succession.
