Geography

| Coordinates: | 29.8° South, 54.2° West (view map) | ||||
| Paleocoordinates: | 49.3° South, 23.6° West | ||||
| Basis of coordinate: | stated in text | ||||
| Geographic resolution: | local area |
Stratigraphy
| Geological group: | Rosário do Sul | Formation: | Sanga do Cabral | ||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: The Sanga do Cabral Fm. is correlated with the "impoverished zone" (Procolophon subzone) of the Lystrosaurus Assemblage Zone of the Main Karoo Basin of South Africa by some authors on the basis of the abundant records of Procolophon, i.e., it is Upper Induan to Lower Olenekian in age (see Dias-da-Silva et al., 2006, Can. J. Earth Sci. and references therein). However, Langer et al. (2007; New Mexico Mus. Nat. Hist. Sci. Bull. 41) pointed out that the prevalence of Procolophon in the Brazilian sequence might represent a taphonomic bias, and that only an undifferentiated Lower Triassic age is currently possible.

Lithology and environment
| Primary lithology: | poorly lithified conglomerate | ||
| Includes fossils? | Y | ||
| Lithology description: Intraformational conglomerate with fine-grained, weakly cemented matrix (Lavina, 1983). | |||
| Environment: | fluvial indet. | Tectonic setting: | cratonic basin |
| Geology comments: The deposits represented by the Sanga do Cabral Fm. "are interpreted as being deposited by braided river systems which poorly confined channels that developed on a low-gradient alluvial plain." (Dias-da-Silva et al., 2006, Can. J. Earth Sci. 43(11)). | |||
Taphonomy
| Modes of preservation: | body,permineralized |
| Size of fossils: | macrofossils |
| Preservation of anatomical detail: | variable |
| Fragmentation: | frequent |
| Encrustation: | none |
Collection methods and comments
| Collection methods: | mechanical | ||
| Reason for describing collection: | taxonomic analysis | ||
| Collectors: | V. Ochagavia da Costa, D. Cargnin | Collection dates: | 1980, 1981 |
| Collection method comments: UFRGS PV = vertebrate paleontology collections of the Universidade Federal do Rio Grande do Sul, Porto Alegre | |||
| Taxonomic list comments:Dias-da-Silva et al. (2005) did not specify the localities for their rhytidosteid temnospondyl material, but Langer et al. (2007) indicated that at least some of it was from the Catucaba locality | |||
