Lithology and environment
| Primary lithology: | paleosol/pedogenic poorly lithified sandy siltstone |
| Includes fossils? | Y |
| Lithology description: La Invernada Formation (Cantú, 1992) is a very fine sandy silt with lenses of coarse sand; these lenses are intercalated by other lenses of very fine sandy silt. The top of this formation is marked by Las Tapias geosol, developed in a loess mantle (La Invernada Forma- tion) and stratigraphically equivalent to the hypsithermal paleosoil of Kröhling (1999a) | |
| Environment: | terrestrial indet. |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
Collection methods and comments
| Reason for describing collection: | biostratigraphic analysis |
| Collection method comments: The fossil material of Río Cuarto was studied by Cruz (2007).
Cruz 2013 re-examined the specimens & stratigraphy of fossil localities of Cordoba including this one. | |
| Taxonomic list comments:The fossil material of Río Cuarto is housed in the UNRC-PV. | |
