Stratigraphy
| Geological group: | Passa Dois | Formation: | Rio do Rasto | Member: | Morro Pelado |
| Stratigraphy comments: "The studied outcrop belongs to the Middle—Upper Permian sequence of the Rio do Rasto Formation, Paraná Basin (Holz et al. 2010)." Formation correlated with the Roadian to Wuchiapingian. | |||||
Lithology and environment
| Primary lithology: | sandstone |
| Secondary lithology: | siltstone |
| Lithology description: The outcrop "displays a succession composed of dominant layers of fine- to medium-grained sandstone, interbedded with siltstone layers with bedding-parallel stratification at the base. At the top of the outcrop, sandstones with tangential cross bedding of typical sigmoidal geometry are present" | |
| Environment: | delta plain |
| Geology comments: "This succession reflects a delta-front depositional environment." | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
Collection methods and comments
| Reason for describing collection: | taxonomic analysis |
| Collectors: | M. C. Barberena |
| Collection method comments: " Fragments of bone elements were found in five different levels of the outcrop, mainly in the siltstone strata and fine- to medium-grained massive or bedding-parallel stratified sandstone." | |
| Taxonomic list comments:"The specimen UFRGS-PV-0355-P was collected in the early 1980s by a team headed by Mário C. Barberena, a former researcher at Universidade Federal do Rio Grande do Sul (UFRGS) and is housed at the Laboratório de Paleontologia de Vertebrados of UFRGS." | |
