Caturrita Formation

The Caturrita Formation is a rock formation found in Rio Grande do Sul, Brazil. Its sediments were deposited in the Paraná Basin. The formation is from the Upper Triassic and forms part of the Santa Maria Supersequence in the upper section of the Rosário do Sul Group.BrasilitheriumB. riograndensisBrasilodonB. quadrangularisExaeretodonIrajatheriumI. hernandeziJachaleriaJ. candelariensisMinicynodonM. maieriRiograndiaR. guaibensisEubrontesIndeterminateRio Grande do Sul, Brazil.Two isolated footprintsAn ichnotaxon; footprints of large theropod dinosaurs.GuaibasaurusG. candelariensisRio Grande do Sul, Brazil.Linha São Luiz'Partial postcranial skeleton and a fragmentary hindlimb.'SauropodomorphMacrocollumM. itaquiiRio Grande do Sul, Brazil.Wachholz sitean almost complete and articulated skeletonAn unaysaurid sauropodomorphSauropodomorpha indet.IndeterminateRio Grande do Sul, Brazil'An incomplete right ilium, uninformative vertebral remains and other indeterminate fragments, plus four isolated and incomplete bones including a possible pubis, an ischium, a possible tibia and a metatarsal IV.'An indeterminate sauropodomorph of uncertain phylogenetic placement, probably 'closer to Plateosauria (...) than to Saturnalia–like basal–most sauropodomorphs'.Sauropodomorpha indet.IndeterminateRio Grande do Sul, Brazil'Three incomplete dinosaur specimens, an isolated sacral vertebra, an articulated left pubis–ischium and an isolated right ischium.'An indeterminate sauropodomorph of uncertain phylogenetic placement, 'probably more primitive than typical ‘prosauropods’ from the Norian-Early Jurassic'.UnaysaurusU. tolentinoiRio Grande do Sul, BrazilSauropodomorphCargniniaC. enigmaticaRio Grande do Sul, BrazilLepidosaurClevosaurusC. brasiliensisSphenodontFaxinalipterusF. minimaRio Grande do Sul, BrazilPterosaurProterochampsaProterochampsidSoturniaS. caliodonProcolophonianSacisaurusS. agudoensisRio Grande do Sul, BrazilSilesauridStereospondyli indet.IndeterminateRio Grande do Sul, BrazilAn incomplete interclavicleAn indeterminate stereospondyl temnospondyl.TeyumbaitaT. sulcognathusRio Grande do Sul, Brazil'Two nearly complete skulls and a partial skull.'Rhynchosaur The Caturrita Formation is a rock formation found in Rio Grande do Sul, Brazil. Its sediments were deposited in the Paraná Basin. The formation is from the Upper Triassic and forms part of the Santa Maria Supersequence in the upper section of the Rosário do Sul Group. The formation received this name, because Caturrita is a neighbourhood (barrio) of Santa Maria.In Portuguese caturrita also refers to the monk parakeet. The sediments of the Caturrita Formation belong to the second unit of the Santa Maria Supersequence and overlie the Alemoa Member of the Santa Maria Formation. The clayey sediments of the Alemoa Member gradually give way to the more sandy, rarely conglomeratic, Caturrita Formation, which finishes with an unconformity. After this erosional event follow the Rhaetian sediments of the Mata Sandstone, the third unit of the Santa Maria Supersequence. The Caturrita Formation was once regarded as a member of the stratigraphically higher Botucatu Formation or was expanded to include the Mata Sandstone.
