Environment
Lithology: conglomerate
Taphonomic context: lake deposit,carnivore accumulation,human accumulation
Archaeology: stone tools
Habitat comments: "on the palaeoshoreline of the Guadix-Baza lake"
"characterised by sandy gravels, product of a sudden event producing high-energy currents"
"The lithic assemblage of BL is mostly comprised of local flint and micritic limestone tools, typical of the Oldowan technocomplex"
"an intense degree of fragmentation and fractured bones. Cut and percussion marks appear on a wide array of taxa, of all sizes, while carnivoran alterations are inter-mixed alongside anthropogenic alterations" but carnivores may "have had a more secondary access to faunal remains"
