Country: Canada
State: Quebec

Coordinate: 45° 28' 18" N, 75° 51' 0" W
Basis of coordinate: stated in text
Geography comments: "within the Gatineau Park limits"
"Three radiocarbon dates were obtained from pieces of charcoal" in the fossiliferous strata, i.e., "8170 60 years BP (TO-7767), 6825 70 years BP (TO-6855) and 5742 120 years BP (TO-6854)"
Climate and habitat
Lithology: sandstone
Taphonomic context: bird accumulation, cave
Habitat comments: fossils are from strata I through III in Unit 4 at the top of the lower infill, which consists "mainly of silt and sand of a brownish colour" with fewer "fine particles" in higher levels (suggesting a dominant sandstone lithology)
"Some" of the animals "lived and died in the cave or that tumbled in and perished there" and others "probably represent animals that were consumed by avian predators" with no apparent mammalian predation
Life forms: carnivores, rodents, other small mammals, snails
Sampling methods: quarry, screenwash
Sample size: 1005
Sampling comments: "The material was excavated using a garden towel" and "brought to the lab for bulk sieving"
at least four species of bats are present and only Eptesicus fuscus is broken out, so bats are omitted
Sample: 3540
