Most paleolithic household activities are thought to have taken place around hearths or fires. The author of the present study chose to examine the Middle Paleolithic site El Salt in Spain, which contains eleven well-preserved and overlapping open-air hearth structures. It was previously unclear whether these hearths were formed during successive short-term site occupations or fewer, longer term occupations. The authors examined the micromorphology of the different layers within the hearth structures to assess occupation timings within the study unit and conducted both a lipid biomarker analysis and isotope analysis to gain information about potential food and fuel.
The results of the analyses show stratified hearths built on multiple different topsoils over different periods of time. The burned organic matter present at the El Salt hearths is rich in herbivore excrement and flowering plant residues. The presence of flint and bone shards, as well as conifer wood charcoal collected from trees not present at the site, provide evidence of limited activity at the site. The authors suggest these data indicate at least four successive short-term Neanderthal occupations separated by relatively long periods of time, potentially based around the seasons.
The authors suggest their molecular and micromorphological methods would work well at similar paleolithic sites where fires were built. Their findings provide evidence for successive short-term Neanderthal occupations at this site, and could inform our understanding of Neanderthal group mobility and settlement more generally.

Sounds to me like a hunting camp.
All except for the herbivore excrement. Anyone does that at my camp and he is hunting by himself next year.
Burning dried dung for fuel is an old school thing.
