Geography
Country: Brazil

State: Pernambuco

Coordinate: 8° 25' 27" S, 37° 43' 20" W
Latlng basis: stated in text

Time interval: Late Pleistocene

Geography comments: in Alagoinha municipality "7 km north from Alagoinha City"
said to be late Pleistocene, presumably based on faunal content

•
Environment
Lithology: sandstone

Taphonomic context: lake deposit

Habitat comments: "tank deposits... The lowermost facies consists of unsorted fossiliferous sandstone (about 3 m thick) composed of angular and subangular quartz grains. This facies overlies the basement rock which forms the floor of the tank. The uppermost lithofacies is an unfossiliferous matrix-supported conglomerate about 1 m thick without any macrofossils... a parautochthonous assemblage that experienced a short time span of subaerial exposure prior to burial and short-distance transport to inside the tanks, unleashed by debris-flows"
the deposit "is pond-like, unlike most other tank deposits"

Methods
Life forms: ungulates, other large mammals, other reptiles

Sampling methods: quarry

Sample size: 230 specimens

Years: 1938 - 1940

Net or trap nights: 0

Basal area status: not applicable

Sampling comments: "excavated from 1938 to 1940 and studied by Vidal, 1946, Vidal, 1955, Vidal, 1959... Two tanks were excavated from 1938 to 1940, however, as they are adjacent, they were here considered as a single fossil accumulation"
