Lithology and environment
| Primary lithology: | not reported |
| Lithology description: Megasequence III, or Araucanense is composed in the CalchaquõÂ Valley of a coarsening and thickening upward cycle, up to 3 km thick, which overlies the Angastaco Formation conglomerates in Megasequence II through a rapid transition zone. Lithology grades from lacustrine and ®ne-grained ¯uvial facies at its base (Palo Pintado Formation), to more proximal ¯uvial and conglomeratic alluvial facies at the top (lower part of the San Felipe Formation), mostly in grayish, yellowish, and greenish strata. | |
| Environment: | fluvial indet. |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils,mesofossils |
Collection methods and comments
| Reason for describing collection: | general faunal/floral analysis |
| Taxonomic list comments:Palinomorphs were not included in the taxonomic list.
The existence of an important fossil content in the Palo Pintado Formation and in the basal section of the San Felipe Formation was known for long time. Russo (1948) mentioned mammal remains belonging to Pleurolestodon avitus, undeterminable plants, and bivalves (Diplodon and Corbicula). Vilela (1954) described from the `Estratos de San Lucas' (equivalent to the Palo Pintado Formation) plant remains (logs and leaves) and the freshwater mollusca Ampularia, Corbicula stelzneri, and Diplodon. | |
