Geography comments: "in the Quercy area... at the junction of the river LOt and its tributary, the Célé"
the entire faunal sequence is bracketed by an ESR/U-series date of 161.3 +/- 14 kyr at the top and two U/Th dates of 229 + 78 - 42 and 202 + 78 - 39 kyr at the base

Environment
Lithology: claystone
Taphonomic context: cave,human accumulation,pitfall trap
Archaeology: stone tools
Habitat comments: a pitfall trap with fossils from "clays, sands, angular limestone rocks"
there is a "very rich archaeological level" immediately above the fossiliferous sequence that dates to the "Early Middle Paleolithic" and there are "scarce and dispersed artefacts of the same age" in the fossiliferous levels
the site "was used for marginal scavenging by Lower Paleolithic hominid groups and as a kill-butchery site during the EMP", so it is at least partially a human accumulation
from stratigraphic units 6a, 7a, 7a', and 7b
there is apparently no sandstone in this interval, so the fossils are presumably from clays

Methods
Life forms: bats,carnivores,rodents,ungulates,other small mammals,lizards,snakes,frogs,salamanders
Sampling methods: quarry,screenwash
Sample size: 3673 specimens
Years: 1994 - 2003
Sampling comments: there was a "rescue excavation" in 1978 - 1980, but the main excavation was between 1994 and 2003
the high abundance of micromammals is taken to mean that screening was used
