Garivaldino (Holocene of Brazil)

Also known as site RS-TQ-58

Where: Rio Grande do Sul, Brazil (29.6° S, 51.6° W: paleocoordinates 29.6° S, 51.6° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Botucatu Formation, Holocene (0.0 - 0.0 Ma)

• Hadler et al. 2008: C14 datings indicate that the sequence integrated for both sites represents the interval Early Holocene (9,400 years BP) – Late Holocene (3,730 years BP; see Table 1).

• group of beds-level stratigraphic resolution

Environment/lithology: cave; sandstone

• Both sites are rock shelters eroded in the sandstone of the Botucatu Formation (Mentz-Ribeiro & Ribeiro, 1999; Dias, 2003).

Size class: macrofossils

Collection methods: Hadler et al. 2008: The material from Garivaldino site is deposited in the UNISC. The excavations at the Garivaldino site were performed at arbitrary levels at 10 cm intervals, comprising twenty-three levels (Dias & Jacobus, 2003). The specimens received compound number (e.g., 1754- 4); the first one (in this case, 1754) indicates the level into a grid from where it was excavated, according to the institutional catalogue numeration for levels and grids. The second number (in this case, 4) indicates the specimen itself, and obeys a sequencial order into a level of a grid.
