Although researchers once considered Ireland’s mammals to have spread to Ireland during the early postglacial from 11,700 cal BP, research has increasingly suggested humans translocated many of these species to Ireland. However, due to sparse evidence, the origin of Ireland’s purported native mustelid species remains unanswered. In this study, we shed light on the history of otter and badger in Ireland by directly dating suspected early examples of these species from Derragh, Co. Longford, a late Mesolithic campsite. The results demonstrate that both of these species have been present in Ireland for at least 7000–8000 years. It is not clear if they represent self-colonisers or Mesolithic anthropogenic translocations. Although these finds do not rule out local extinction and later reintroduction, they show that we can no longer assume they are solely late Holocene introductions.","PeriodicalId":44025,"journal":{"name":"Science and Technology of Archaeological Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135864095","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We found little correlation between the quantity of calculus analysed and total protein identifications, as well as no systematic trends between site location and protein preservation. We identified a wide range of individual variability, which may be associated with the mechanisms of calculus formation and/or post-depositional contamination, in addition to taphonomic factors. Our results suggest dental calculus is indeed a stable, long-term reservoir of proteins as previously reported, but further systematic studies are needed to identify mechanisms associated with protein entrapment and survival in dental calculus.</p>","PeriodicalId":44025,"journal":{"name":"Science and Technology of Archaeological Research","volume":null,"pages":null},"PeriodicalIF":3.5,"publicationDate":"2017-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20548923.2017.1361629","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35219641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
