Environment
Lithology: claystone
Taphonomic context: cave,fluvial deposit,pitfall trap,rodent accumulation
Habitat comments: "more likely a fissure deposit"
the material is from layers L7 ("Light brown loose sandy clay") and L8 ("Brown sandy clay")
there are "mostly isolated teeth" and "few bone fragments without any complete long bones" and there are "either gnawed or rounded marks" on the specimens
there are no "human fossils or artefacts"
"rodents were the last accumulator agents before burial" but the material is mostly water-transported, and some specimens "most likely dropped and trapped"

Sample size: 527 specimens
Years: 2000
Sampling comments: the excavation was "in an area of about 5 m2, and excavated by intervals of 10 cm"
"50 kg of sediments were water-screened to collect micromammals using 35 mm mesh sieves" but only the teeth of the "medium-large mammals" are reported here
