Environment
Lithology: sandstone
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
"LM Unit II is composed of poorly stratified massive sand"
There are low levels of water abrasion, indicating a small amount of modification by low-intensity water flows
Weathering on remains is low (22.2%), and what is present is "stage 1" which indicates rapid burial at the site
"Percussion pits" were identified on 4 remains, indicating some level of access by hominins to the carcasses, as does the presence of some stone tools
Carnivore marks are seen on 36 faunal remains
