Environment
Lithology: siliciclastic (mixed)
Taphonomic context: fluvial deposit,human accumulation
Habitat comments: "an archaeological settlement with plenty of elephant remains interpreted classically as a kill and butchering site" but "We propose that Ambrona is an elephant natural burial site, many remains have been transported while others remained in situ... Nevertheless, some of the animal remains appear to have been butchered or scavenged by man"
AS1 consists of "sands and gravels, fluvial environment" (Sânchez-Romero et al. 2016)
lithics may or may not be present at this level
