Extract

Huene (1935) first reported dicynodonts from the Triassic Santa Maria Formation of southern Brazil. Most common are specimens of Dinodontosaurus from localities near Chiniquà (Chiniquà local fauna) and near Candelaria (Candelaria local fauna) in the state of Rio Grande do Sul. The other Middle Triassic dicynodont found near Chiniquà is the huge (about 3 m body length) Stahleckeria potens, and an equally large Middle Triassic dicynodont, Barysoma lenzii, is known from near Candelaria. A fourth, supposed Santa Maria Formation dicynodont, Jachaleria candelariensis (Araújo and Gonzaga, 1990), is actually from a younger, Upper Triassic, horizon of the Caturrita Formation near Candelaria (Bonaparte, 1982). Here, I argue that Barysoma lenzii is a junior subjective synonym of Stahleckeria potens and discuss the biochronological significance of this synonymy.
