Testing sample selection criteria and loss of biomarkers during cleaning of archaeological unglazed pottery to maximize organic residue quantities

open access: yesArchaeometry, Volume 67, Issue 3, Page 536-551, June 2025.
Abstract As the number of studies in organic residue analysis (ORA) of ancient pottery—a sensitive but as of today also a destructive method—increases, archaeologists are interested in knowing which samples promise the biggest abundance of analytes in order to avoid unnecessary loss of artefacts.

Applying sterols and bile acids as biomarkers for identifying human versus wild animals' faecal traces in cave sediments at archaeological sites

open access: yesArchaeometry, EarlyView.
Abstract Faecal biomarkers are used to trace and identify the source of faecal matter at various types of archaeological sites. Until now, the focus has been centred on humans and domesticated animals. However, in caves, it's wild animals that play a role in the deposition of organic matter.
