 thumb|estimated size of saturnalia, compared to a human. saturnalia is an extinct genus of basal sauropodomorph dinosaur known from the triassic of rio grande do sul, southern brazil. == discovery == saturnalia was originally named on the basis of three partial skeletons. the holotype, mcp&nbsp;3844-pv, a well-preserved semi-articulated postcranial skeleton, was discovered in mid-summer at sanga da alemoa, rio grande do sul, in brazil, in the geopark of paleorrota. the two paratypes are mcp&nbsp;3845-pv, partial skeleton including natural cast of partial mandible with teeth and some postcranial remains, and mcp&nbsp;3846-pv, partial skeleton including postcranial remains. all specimen were collected in the "wald-sanga" (also known as "sanga do mato") locality from the alemoa member of the santa maria formation (rosÃ¡rio do sul group), dating to the carnian faunal stage of the early late triassic, about 225&nbsp;million years ago. a partial femur from the carnian pebbly arkose formation of zimbabwe was also attributed to the genus. it is one of the oldest true dinosaurs yet found. it probably grew to about 1.5&nbsp;meters (5&nbsp;ft) long. ==etymology== saturnalia was first named by max c. langer, fernando abdala, martha richter, michael j. benton in 1999 and the type species is saturnalia tupiniquim. the generic name is derived from saturnalia, latin for "carnival", in reference to the discovery of the paratypes during the feasting period. the specific name is derived from portuguese and guarani word meaning native. ==phylogeny== the primitive nature of saturnalia, combined with its mixture of sauropodomorph and theropod characteristics, has made it difficult to classify. paleontologist max cardoso langer and colleagues, in their 1999 description of the genus, assigned it to the sauropodomorpha.langer, m.c., abdala, f., richter, m., and benton, m.
