Geography comments: Barranc de la Boella is located 6 km from the Mediterranean coast in a ravine in the town of la Canonja (Tarragona)

EF4 is located in Unit II of El Forn, below EF3

Unit II was dated using palaeomagnetism and cosmogenic nuclides dates

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
