Geography
Country: Chile


Coordinate: 34° 29' S, 71° 10' W
Coordinate basis: estimated from map

Formation: Laguna de Tagua Tagua

Time interval: Late Pleistocene

Max Ma: 0.01138

Min Ma: 0.010578

Age basis: radiocarbon (uncalibrated)

Geography comments: there are uncalibrated dates of 11,380 +/- 20 and 11,000 +/- 250 ybp on the same sample of charcoal; 10,578 +/- 48 ybp on "charred megafauna bone"; and 10,738 +/- 43 on charcoal
calibrated dates are definitely Late Pleistocene

Environment
Lithology: siltstone

Taphonomic context: human accumulation,lake deposit,paleosol

Archaeology: bone tools,stone tools

Habitat comments: the formation includes "lacustrine greenish, brownish and grayish massive to laminated clays and silts with some diatomaceous inclusions" and TT-1 "cultural materials and faunal remains were mainly recovered at the base of member 6 in which a discontinuous paleosoil was detected, but also at the top of the member 5"
Fig. 1 indicates that the sediments are clayey silts
"Lithic tools and debitage, as well as bone tools were discovered spatially associated with fossils... Montané (1968) also mentioned several bone tools made on horse bone, including flakers. No hearths were detected, but scattered charcoal spicules were found. In sum, all the evidence suggests a short-term camp in which mammal-processing activities were carried out... The anthropic marks observed in horse and cervid bones suggest that these taxa were culturally deposited"

Methods
Life forms: carnivores,rodents,ungulates,other small mammals,birds,snakes,frogs,fishes,snails

Sampling methods: quarry

Sample size: 988 specimens

Sampling comments: "TT-1 was archaeologically excavated during two field seasons (late 1960s and early 1990s), accounting for a total of around 189 m2 of excavated area"
