Abstract
A new Triassic vertebrate fauna, known from over 100 specimens, is dominate d by non-mammalian cynodonts. Three specimens represent sectorial-toothed c hiniquodontids, while thirty-nine are traversodontids, of at least, four di fferent types that are distinguished principally by postcanine morphology. The Santa Cruz do Sul is the only locality within the Santa Maria Formation characterized by the prevalence of cynodonts, and importantly documents a high traversodontid diversity for the South American Triassic.
