Gas chromatography-mass spectrometry (GC-MS) is routine for identifying the organic compositions and biomarkers. In recent years, liquid chromatography-tandem mass spectrometry (LC-MS/MS) has been increasingly applied to discern metabolites with more precision. However, the combination of these two techniques has never been reported in organic residue analysis to date. In this study, we, for the first time, introduce a new method to detect organic residues absorbed in pottery at the Peiligang site (Henan, China) during the Neolithic and Bronze Ages. The results show that compared to traditional methods (GC-MS), the metabolomic analysis (DPMA), combined with on GC-MS and UPLC-HRMS, enables rapid and comprehensive characterization of significant organic compounds in pottery. GC-MS analysis shows the lower content of lipids (0.5–40 μg/g) in all samples, including fatty acids, fatty alcohols, monoacylglycerols, while DPMA analysis indicates the presence of more lipids including fatty acyls, sterols and their derivatives, prenol lipids, polyketides among which fatty acyls are dominant. Both methods suggest that terrestrial animal and plant resources were utilized by humans, but DPMA provides more evidence on the categories of animal and plant resources. Neither method detected the cereal biomarkers (e.g. miliacin), although they were shown in archaeobotanical and dental calculus analyses. This could have been attributed to the timeline of the development of agriculture or the inertness of extraction to plant biomarkers. It is most striking that DPMA analysis finds the secondary metabolites of aromatic plants (13-tetradecanolide, tephrosol, and coumarin A, etc.), might indicating the intentional addition of herbal plants to enhance the flavour during food processing. The universal presence of organic acids in all pottery (cooking and non-cooking) in DPMA analysis supports the previously reported claim that they are not unreliable biomarkers related to alcohol-making activities. Furthermore, the discriminating analysis of metabolites among all pottery indicates the functional difference between cooking and non-cooking pottery and emphasizes the possible importance of <em>Ding</em> among pottery assemblages. Overall, DPMA has been proven as a novel method to look through culinary practices with highly sensitive resolution and has great potential in expanding our knowledge of ancient culinary practices. At last, the advantages and disadvantages of applying DPMA analysis are also discussed.</div></div>","PeriodicalId":50254,"journal":{"name":"Journal of Archaeological Science","volume":"184 ","pages":"Article 106415"},"PeriodicalIF":2.5,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145425277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, challenges in identifying their remains in the archaeological record have constrained our understanding of their significance. Fais, a raised coral island in Micronesia, has been inhabited for 1800 years, with archaeological evidence revealing a reliance on fishing strategies targeting inshore taxa but also pelagic taxa including some species of sharks and scombrids. Using ZooMS, this study analysed archaeological bones, mostly vertebrae, from the Powa (FSPO) archaeological site, Fais, with 100 % and 93 % success rates of retrieving collagen fingerprints in scombrids (&lt;em&gt;n&lt;/em&gt; = 77) and sharks (&lt;em&gt;n&lt;/em&gt; = 54) respectively. The scombrids were overwhelmingly dominated (97 %; &lt;em&gt;n&lt;/em&gt; = 75) by skipjack tuna (&lt;em&gt;Katsuwonus pelamis&lt;/em&gt;), with the remaining specimens deriving from two distinct species, yellowfin tuna (&lt;em&gt;Thunnus albacares&lt;/em&gt;) and wahoo (&lt;em&gt;Acanthocybium solandri&lt;/em&gt;). In contrast, the shark remains were more taxonomically diverse and evenly balanced, with at least five distinct taxa across much fewer samples. Although lacking a complete enough reference database to make confident assignments to species, we could infer that at least more than one half of the identifications were to groups that closely match the silky shark (&lt;em&gt;Carcharhinus falciformis; n = 20&lt;/em&gt;), and the Galapagos shark (&lt;em&gt;C&lt;/em&gt;. &lt;em&gt;galapagensis; n = 11&lt;/em&gt;); these two sharks have well-known associations with tuna and their identifications are consistent with some of the dominant species inferred through morphology. A third relatively abundant type (&lt;em&gt;n&lt;/em&gt; = 17) yielded spectra that could not be matched to our reference material, though plausibly of the only other relatively abundant tuna-associated taxon, the silvertip shark (C. &lt;em&gt;albimarginatus&lt;/em&gt;).

Nonetheless, the categorization of the shark remains in this study using ZooMS disagrees with the categorization by morphology reported elsewhere, where multiple ‘types’ are found in previously identified morphological types and &lt;em&gt;vice versa&lt;/em&gt;. From a methodological viewpoint, this study clearly demonstrates the substantial difference in confidence that can be assigned to a taxonomic identification that well-curated ZooMS databases can offer, particularly when supported by genomic sequence information.

Here, we summarize the preservation and translocation mechanisms of DNA in sediments, analyze how to face and assess the impact of the translocation problem when applying sedaDNA to archaeological cultural deposits, and propose: 1) to develop appropriate sampling strategies based on site-specific conditions; 2) to apply soil micromorphological and stratigraphic analysis to sedaDNA studies; 3) to conduct systematic comparisons between layers; 4) to conduct more translocation and adsorption simulation experiments; and 5) to carefully interpret results combining other traditional approaches. These need interdisciplinary collaboration among experts in molecular biology, archaeology, soil science, and related fields across multiple stages, including methodological design, sampling, laboratory procedures, and data interpretation.

Procedural depth was distinguished into conservative units (PU_C), indexing routine, reversible steps, and non-conservative units (PU_NC), indexing irreversible, dependency-laden operations with higher executive demands. Ordinary least squares and cluster-robust regressions reveal positive associations between both PU measures and ECV, with PU_NC providing the more consistent predictor (R² ≈ 0.50). Temporal analyses show gradual increases in PU_C, PU_NC, and ECV over ∼2.4 million years, with steep acceleration of PU_NC and brain volume in the Late Pleistocene.

Independent experimental and neuroimaging research further supports this interpretation, showing that complex knapping engages frontal executive networks and increases working-memory and planning demands.
