Cynodonts constitute a conspicuous group of synapsids within Triassic continental faunal assemblages. The fossil record of cynognathians (including traversodontids) and non-mammaliaform probainognathians is conspicuous in South America, especially in western Argentina and southern Brazil, representing the cornerstone to understand Middle to Late Triassic cynodont evolution. In this contribution we present an overview of South American non-mammaliaform cynodonts and some taxonomic and biostratigraphic comments.
