The identification of manure and faecal materials in archaeological soils from Crete, Turkey, Athens, and Orkney
Researchers at the Organic Geochemistry Unit, University of Bristol have been used stanols, sterols and other organic biomarkers to identify the presence of faecal material and manures in soils from Orkney and Crete. In Orkney the addition turf and human and to a lesser extent pig faecal material was identified in buried anthropogenic soils dating to the Late Neolithic and Bronze Age at Tofts Ness through comparison with modern control and reference samples (Bull et al. 1999; Simpson et al. 1998). Soils from agricultural terraces dating to the Minoan Period on Pseira Island, Crete also contained evidence of human faecal material suggesting systematic faecal deposition and manuring (Bull et al. 2002).

At &Ccedil;atalh&ouml;y&uuml;k in Turkey organic geochemistry was used to look at faecal matter in middens and possible animal pens. Human faecal material was detected in the middens but steroidal concentration were too low in the suggested animal pens for further interpretation despite micromorphological evidence of animal dung from these contexts (Bull et al. 2005).

Finally the team also used faecal biomarkers to study the abandonment of a subterranean stone built culvert at the Agora, Athens, Greece. Human faecal indicators were in the highest concentrations in the lowermost fills of the culvert. The decrease in concentration up through the profile was indicative of the culvert falling out of use relatively rapidly, possibly at the time of the Slavic incursion in AD 582-583 (Bull et al. 2003).
