Reference: R. A. Fariña, P. S. Tambusso, L. Varela, A. Czerwonogora, M. Di Giacomo, M. Musso, R. Bracco, and A. Gascue. 2013. Arroyo del Vizcaíno, Uruguay: a fossil-rich 30-ka-old megafaunal locality with cut-marked bones. Proceedings of the Royal Society B 281(1774):1-6 [ER 3790]

Lithology: siliciclastic (mixed)

Taphonomic context: fluvial deposit,human accumulation

Archaeology: stone tools

Habitat comments: almost all specimens are from bed 2, but "some reworked elements are found in bed 3"
bed 2 fines "upwards... from a greenish muddy sandy gravel (facies a) to a brownish muddy sand (facies b)" and is "compatible with a fluvial system deposit"
"fluvial agency can be ruled out as the main source of the accumulation" and there was "fast burial, perhaps as a single event" that is interpreted as "biogenic" and "particularly human"
"40 elements... show marks that have macroscopical features consistent with human agency"
a stone "possible scraper" was found "in very close association with several bones" and there are a few other apparent lithics
despite the date of the deposit, the paper generally argues that this is a kill site (human accumulation + stone tools) although the authors do not firmly conclude this
