When fossils are discovered, exposure to the humidity and oxygen in the air begins a destabilization of the minerals and activation of chemical oxidation. In the last century, it was common practice to protect fossils by covering them with unspecified commercial varnish, but today it is clear this method is useless for long-term preservation. Moreover, varnish obliterates the precise features of teeth and bones, usually preventing researchers from correctly analysing and describing these specimens. In this paper, we describe the methodology applied for conserving fossils identified as Anthracotherium magnum, discovered in lignite deposits of Chiuppano (Vicenza, Italy) in the mid-twentieth century. We pre-prepared the specimens, removing varnish from the fossil surfaces, and we exposed them to an aerosol solution of PEG400 and concentrated ammonia. We discuss the colour shift of bones and the rediscovery of anatomical characteristics to underline the importance of prompt action in the preservation of fragile specimens for future exhibition.","PeriodicalId":92401,"journal":{"name":"Journal of conservation & museum studies","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43681667","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}

However previous studies have shown that many collections are underutilized within university settings. The purpose of this paper is to examine contributing and detracting factors for use. In-depth, semi-structured interviews were conducted with curators and collection managers (n = 15) at twelve institutions. Respondents were then asked to recommend faculty members who did (n = 9) or did not use the collection (n = 6). Through data analysis, four major themes were related by the collection managers including: 1) ambiguous roles and unknown collections, 2) continual need for collection management maintenance, 3) lack of process and access to the collections, and 4) misperceptions about the collections. Faculty that used the collection (n = 9) stated previous knowledge of the collection and the importance of material culture to student knowledge and understanding. Barriers as identified by those faculty that did not use the collection (n = 6) included lack of access and difficulty in scheduling time to use the collections.","PeriodicalId":92401,"journal":{"name":"Journal of conservation & museum studies","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44152315","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}

Little is known about the diversity or sources of these shells. Here, we document the diversity of mollusk shells present in the WT and use data on their characteristics to make inferences about their provenance. We identified shells of 34 species, 24 of them bivalves (clams and their relatives) and 10 gastropods (snails). Almost all (29/34) of these species are native to southern California shorelines, especially those of bays and estuaries. Rodia could have accessed these sites on foot, by automobile, or by using the Red Car trolley system. Some of the bivalve shells bear drill holes made by naticid gastropods, suggesting that they were collected post-mortem, presumably after they had washed up on beaches. These observations are consistent with the sparse documentary evidence on the origin of the shells of the WT. This detailed information on the diversity of the seashells of the WT should be of utility to conservators, and of interest to scholars of and visitors to the WT.","PeriodicalId":92401,"journal":{"name":"Journal of conservation & museum studies","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41454089","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}
