Unfortunately, the history of dog sledding is difficult to trace in archaeology. The identification of dog sledding in the past has been mostly addressed through the association of dog skeletal remains with material parts of sleds and harnessing equipment. However, there is currently no method for identifying sled-pulling activity directly from canid remains. This article introduces a new visual scoring manual for entheseal changes to address this gap in knowledge. Entheseal changes are morphological variations to entheses<em>,</em> which are muscle, tendon, and ligament attachment sites on bone. They have been used to reconstruct past activity in humans and, more recently, reindeer and equid remains, but never in canids. This method was developed for thirteen entheses on the forelimb and hindlimb using 74 working sled dogs, non-working pet dogs, and wild canids. Visual scores were compared to examine the effect of activity on entheseal changes, but also confounding biological factors such as age, sex, and body size. Observer error tests were also conducted to determine the method's precision and repeatability. The results show that sled dogs have significantly higher scores than non-working canids, especially for seven attachments. This suggests that entheses are morphologically sensitive to habitual sled-pulling, though some attachments are better indicators of working activity than others. Overall, these findings demonstrate that the method can differentiate sled dogs from pet dogs and wild canids and is a useful tool for identifying sled-pulling activity in archaeological canid remains. Furthermore, this method will help to better understand the history and development of human-dog relationships in the North.</div></div>","PeriodicalId":50254,"journal":{"name":"Journal of Archaeological Science","volume":"177 ","pages":"Article 106204"},"PeriodicalIF":2.6,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143600575","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 morphometry of scallop shells is highly structured geographically, showing differences between lagoons of origin regardless of the period. This archaeobiogeographical pattern allows for the estimation of the geographical origin of valves discovered in the hinterland and the reconstruction of marine resource provisioning centres. While most valves were sourced as close as possible to the place of consumption, the exception of the smooth scallops from the city of <em>Nemausus</em> (Nîmes) reveals a structured network dedicated to urban supply.

Furthermore, the lack of tunnelling features in Mesolithic hearth features cannot be explained by archaeologists not digging deep enough, as such tunnels also extend laterally from an ant nest. The biological features observed in the Doel excavations do not match the morphology of ant tunnels.
