Geography
Country: Ethiopia



Coordinate: 10.477° N, 40.443° E
Coordinate basis: estimated from map

Scale: quarry

Formation: Sagantole

Time interval: Early Pliocene

Max Ma: 4.419

Min Ma: 4.416

Age basis: Ar-Ar

Geography comments: from the Lower Aramis Member of the Sagantole Formation in "the Central Awash Complex (CAC) of the Middle Awash study area" (WoldeGabriel et al. 2009)
the exact location is shown in Fig. 1 of WoldeGabriel et al. (2009
"The Aramis Member directly overlies the Gŕala (“Camel”) Tuff Complex (GATC), which has a 40Ar/39Ar age of 4.419 ± 0.068 Ma" and is "overlain by the Daam Aatu (“Baboon”) Basaltic Tuff (DABT), which has a 40Ar/39Ar age of 4.416 ± 0.031 Ma" (WoldeGabriel et al. 2009)

Environment
Lithology: claystone

Taphonomic context: overbank deposit,bird accumulation

Habitat comments: the member consists of "silt, clay, and sand of variable thickness and induration, deposited on a floodplain" (WoldeGabriel et al. 2009) and the fossils are specically from "alluvial silty clay" according to White et al. (2009)
a "partially in situ" skeleton of Ardipithecus ramidus was collected, but most material was disassociated (Louchart et al. 2009)
there is no evidence of "hydraulic transport" but is marking of bone by mammalian carnivores, crocodiles, rodents, and insects, and "many of the microvertebrate remains [in the two main quarries] may have been disaggregated from barn owl (Tyto) pellets" (Louchart et al. 2009)

Methods
Life forms: carnivores,primates,ungulates,other large mammals

Sampling methods: quarry,screenwash

Sample size: 326 specimens

Sampling comments: quarried and collected by "team crawls" and by "water-sieving" (Louchart et al. 2009)
indeterminate bovids identified to tribe are also enumerated
"Remains of lizards, snakes, and frogs were recovered, particularly at the ARA-VP-6 microfauna quarry" and fish, crocs, and turtles are also present in the member (WoldeGabriel et al. 2009)
White et al. (2009) also mention an Aquila "and other birds", and small mammals are present according to Louchart et al. (2009)
fossil wood, pollen, gastropods, a centipede, dung beetle broodballs and a nest, and coprolites are discussed by WoldeGabriel et al. (2009)
