摘要：

In this paper, we describe new postcranial remains of Chiniquodon cf. C. thetonicus, a chiniquodontid cynodont from the Therapsid Cenozone, from the Santa Maria Formation. Middle Triassic Of Southern Brazil. In the described specimen are preserved almost all presacral vertebrae, the sacral vertebrae, an incomplete pelvic girdle, the left femur, and two metapodials. Some of these bones show slight differences relative to those already described for C. theotonicits, especially in the femur and in the pelvic girdle. Since the species can actually include the materials attributed to the genera Probelesodon (except from P sanjuanensis) and Belesodon. however. these differences may represent normal ontogenetic variation in the species rather than being of taxonomically diagnostic value.
