The most well-known example is the Venus from Dolní Věstonice I in the Czech Republic, which is the biggest and best-preserved human figurine made from clay. Due to its high cultural value, exploration of the internal structures of this figurine has represented a huge challenge, as only non-destructive methods could be applied. Thanks to tremendous technological advancements, we were able to use high-resolution micro-CT imaging. This imaging revealed the structural compositions of the ceramic paste, the technology of the statuette's shaping procedure, and the taphonomy of this piece of art. We reveal that the ceramic paste was prepared from loess sediment containing stones, microfossils, and carbonate aggregates from the basement complex as an natural admixture. The particles are randomly distributed. We did not find any bones or ivory remnants inside the body. Missing joined areas of different parts of the body of the Venus indicate that the figurine was made from a single piece of clay using the non-additive method of shaping. The internal cracks in the body of the Venus statuette represent the main feature of its taphonomy and influence the way it will be manipulated in the future.</p></div>","PeriodicalId":50254,"journal":{"name":"Journal of Archaeological Science","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141949531","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}

This study develops a simple and non-destructive ageing method based on a suture and synchondrosis obliteration using a sample of over 700 modern dog crania. Scoring the extent of obliteration of individual sutures provides a valuable means of differentiating adult and juvenile crania. Combining the scores for multiple sutures permits the assignment of dog crania to an age group, albeit with less certainty among middle-aged and older adults. Breed, crania shape, sex, and body size all likely create variation in suture obliteration patterns and their relationships to dog age.

{"title":"Studying seriality in material culture by geometric morphometrics–gold wild boars from the Arzhan-2 barrow, Tuva","authors":"","doi":"10.1016/j.jas.2024.106021","DOIUrl":"10.1016/j.jas.2024.106021","url":null,"abstract":"<div><p>In the field of material culture, seriality refers to the serial production of nearly the same object in terms of shape and size, yielding visually identical artefacts. Subtle variations may nevertheless occur, depending on the technologies used, or the number and reliability of moulds, for example. Geometric morphometrics based on landmark analysis, along with accompanying statistical techniques, provides methods well-suited for identifying small but archaeologically significant variations in shape and size within such datasets. In this study, we exemplify the efficiency of geometric morphometrics in a context of seriality, using a large series of centimetric-sized gold wild boars decorating a case for bow and arrows, discovered in the Arzhan-2 barrow of the early Scythian time. A total of twenty-seven 2D landmarks was collected for each specimen to assess the level of similarity between individuals with high precision, and to investigate the presence of subgroups, possibly indicating the use of several models. However, due to the homogeneous nature of the dataset, notable measurement errors may obscure the sought-after archaeological signal. To mitigate this, each specimen was measured twice by three different operators. Boas coordinates of the six replicates were then averaged, resulting in a reduction of the effect of measurement errors. Two distinct shape groups are identified, consisting of an approximately equal number of individuals. These findings suggest that the entire set of wild boars could have been produced <em>via</em> two separate manufacturing chains, possibly running in parallel, where two distinct, albeit very similar, solid models were involved. Within each group, discreet variations in size were observed. They are probably due to variable shrinkage during casting. These observations would have been difficult for the naked eye, even for an expert in the field, because the striking similarity within the series and the post-processing by the goldsmith obscure the shape signal originating from the moulds. Besides the original information provided here about the gold wild boars of Arzhan-2, it is worth emphasizing that the use of these techniques should be encouraged, particularly when applied to the study of seriality. The workflow described can easily be reproduced and adapted for almost any serially produced archaeological assemblage.</p></div>","PeriodicalId":50254,"journal":{"name":"Journal of Archaeological Science","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S030544032400089X/pdfft?md5=37a606c4757462023cf7068ba3fa53e7&pid=1-s2.0-S030544032400089X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141949533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nitrogen isotope system has been extensively applied to the human bioarchaeological record to predict dietary protein sources, as nitrogen isotope ratios roughly track the trophic positionality of an organism. While the ratio of nitrogen isotopes in organisms (δ¹⁵N) tends to be reflective of trophic position, nitrogen isotope fractionation is complex and subject to many sources of variation. This study explores how human behavior might influence this variation. We experimentally investigated the impact of food-related behaviors on the δ¹⁵N dietary proxy, with specific focus on selection and processing of animal food sources. In assessing putrefaction, processing, prey choice, and fuel wood, we saw that these variables generated small shifts of ∼1.5‰ or less in the δ¹⁵N values of food items. We conclude that scavenging as a frequent dietary adaptation may be isotopically visible, but the timing of carcass scavenging likely matters. We also posit that prey species and fuel wood species might matter for the patterning of δ¹⁵N shifts produced by different types of cooking. The results of this study expand the range of contributing factors to consider when utilizing the nitrogen isotope dietary proxy and open new testable questions about the use of this method in populations where complex food behavior may be common.</p></div>","PeriodicalId":50254,"journal":{"name":"Journal of Archaeological Science","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141729453","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}

Recent years have seen an explosion of lidar data collection, and machine learning provides a way to exploit these lidar data, making feature analyses more efficient and consistently executed. At present, there are a limited number of small, area-specific models that exist for the Maya area, the largest of which covers 230 km². Here we present the foundation for a broadscale, multi-area-based convolutional neural network (CNN) object detection model that uses airborne laser scanning data, or lidar, for archaeological feature detection across 615 km² of the Maya area, as well as preliminary results from an additional 885 km² test area. This sets the path for a model that will enable researchers to map archaeological areas across the entire Maya Lowland area in weeks or months instead of decades. Notably, we find that a model trained on multiple areas with significantly different topographies produces better results for all areas as compared to a model trained on a single area. The broadscale model here presented produced an F1 score of 0.80. Results also include many potential new structure detections, including detections on lidar at an archaeological area that has not yet been comprehensively ground-surveyed and is located in an entirely different country in the Maya Lowlands from where the model was trained on. This model represents an attempt at a broadscale machine learning approach for archaeological feature mapping in the Maya area and demonstrates how big data can be integrated into traditional archaeological workflows.

The copper melting and refining slags, characterized by ²⁰⁶Pb/²⁰⁴Pb around 18.0 and very low lead concentrations (＜4,000 ppm), provided the first reliable indicator about the geological origin of copper used in the Middle Shang period.

Items including alloying slags, dross, spillages and bronze objects have similar HRL characteristics to the Middle Shang bronzes from other sites.

A potential target for studies of ancient beer production are residues formed during brewing activity, including beerstone, a calcium oxalate residue. Here, we apply shotgun proteomics analyses to a sample of modern beerstone to explore this residue's capacity as a marker for beer in archaeological contexts. The beerstone proteome was compared to the protein profiles of ungerminated and germinated barley to identify key proteins indicative of malted grains which may be encased by the residue. Proteins matching to barley grain (<em>Hordeum vulgare</em>) and Baker's/Brewer's yeast (<em>Saccharomyces cerevisiae</em>) were successfully identified in the beerstone. In particular, we identified hordeins, lipid transfer proteins, trypsin/α-amylase inhibitors, and protein Z, which are barley proteins abundant in proteomic characterisations of beer. In comparison to ungerminated and germinated barley grains, we find that beerstone preserves only a subset of the barley proteome, with the residue being more reflective of the final brewing product than of earlier brewing steps such as malting.
