Geography
Country: South Africa

State: Free


Coordinate: 27° 14' 3" S, 28° 51' 3" E
Coordinate basis: based on nearby landmark

Time interval: Early Pleistocene

Max Ma: 1.06

Min Ma: 0.9

Age basis: paleomag

Geography comments: coordinate based on Cornelia
assigned to the Jaramillo subchron based on paleomagnetic stratigraphy, which is said by the authors to span "1.07 and 0.99 Ma" but is currently 1.06 to 0.90 Ma

Environment
Lithology: siliciclastic (mixed)

Taphonomic context: carnivore accumulation,fluvial deposit

Archaeology: stone tools

Habitat comments: "valley-fill, alluvial and colluvial fossil-rich gravels and clays" with most fossils from "the Mottled Yellow Clay (MYC, Butzer's Bed 2)... a densely-packed bone bed" that was "accumulated on a palaeosurface within an abandoned channel... the primary agent of accumulation was a large bone-gathering predator, possibly spotted hyaenas"
there are "Acheulian artifacts" that are listed in detail in Table 2

Methods
Life forms: carnivores,primates,ungulates

Sampling methods: quarry

Sample size: 605 specimens

Sampling comments: the bone bed was "systematically excavated" during this period
