Environment
Lithology: siliciclastic (mixed)
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 II contains "poorly stratified sand and gravel"
Relatively high levels of abrasion are seen at EF4 (24.4%), mostly Stage 1 indicating limited exposure to low-intensity water flows
Relatively low levels of weathering are seen at EF4 (29.5%), mostly associated with dry fractures (75.3%)
Stage 1 weathering was predominant in EF4 indicating short exposure and low degree of destruction
Lithic artifacts were found at EF4 indicating some level of hominin presence
Carnivore tooth marks were present on 11% of the remains at EF4
