Salla, Bolivien


Fundort: Salla, Bolivien, , Bolivien
Taxon: Branisella boliviana aus der Familie Cebidae
Fossilien und Beschreibung der Fundstelle:
Macrofossils,mesofossils, See MacFadden et al. (1985:225–227) for a description of stratigraphy. They recognized a number of distinct fossil-bearing levels, several of which comprise more than one locality. Kay et al. (1998) revised the age of the fauna and introduced a new stratigraphic scheme that divides the Salla Beds into Units 1 (lowest) through 10 (highest). From highest to lowest, the stratigraphy and principal fossil-bearing levels can be summarized as follows (MacFadden et al., 1985; Kay et al., 1998): - Unnamed unit of thin, probably Pleistocene deposits that locally cover the fossil-bearing strata - Unit 10 - Unit 9. Kay et al. (1998) place the Oligo-Miocene boundary near the top of Unit 9. - Unit 8 - Unit 7 - Unit 6, Upper White Level - Unit 5, Branisella level - Unit 4, Principal Guide Level - Unit 3 with 170 m level ("Red Rodent Zone") and 100 m level - Unit 2 with 30-45 m level - Unit 1 - Luribay Conglomerate, underlying Eocene unit
