Environment
Lithology: mudstone
Taphonomic context: fluvial deposit
Archaeology: stone tools
Habitat comments: Barranc de la Boella formed in a "fluvio-deltaic sedimentary environment"
The sites are located in "fluvial and debris flow" deposits
"Unit III consists of massive mud"
29.2% of EF1 remains are abraded (mostly stage 1), indicating limited exposure to low-intensity water flows, however, EF1 has the highest percentage of abraded elements and 10.3% above Stage 1
Low levels of weathering (30.4%) are seen in EF1, mostly associated with dry fractures (75.5%)
Stage 1 weathering was predominant in EF1 indicating short exposure and low degree of destruction
Percussion pits and lithic artifacts were found at EF1 indicating some level of hominin presence
Carnivore tooth marks are present on 4.5% of EF1 remains
