Held in Edinburgh, this collection is largely comprised of material from the Wanlock- head base-metal mineral veins, and particularly from the Glencrieff Mine. Its approximately 840 specimens represent a century of collecting, from the 1830s to the 1930s, and include a wide range of mineral types, gangue, host rocks, processed ore and smelter residues; some rare mineral species were tentatively identified by the original collectors. These individuals may have been from the several generations of the Wilson family thought to have been involved with the Wanlockhead mines. Liaison with the Edinburgh Geological Society es- tablished that the collection had been passed to BGS in the 1950s by their descendant and active Society member, David Lawson Wilson. He is not known to have had any personal involvement with Wanlockhead so may have acquired the collection through family connections and then added specimens of broader provenance. Not all the items catalogued were strictly geological and these exceptions included two surprising First World War souvenirs.","PeriodicalId":203203,"journal":{"name":"Geological Curator","volume":" 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138616916","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}

These “microfossil” taxa are gener- ally confined to their local habitat and therefore provide insight on the nature of past environments and long-term ecosystem change. For decades, the La Brea Tar Pits (LBTP) in Los Angeles, Califor- nia, USA, has incorporated volunteer sorting of microfossils in their daily research agendas to sup- port scientific discovery in their onsite Fossil Lab. A recent grant-funded research project provided an opportunity to study the Rancho La Brea (RLB) microfossils while extending this “community science” activity beyond the walls of the museum and into local classrooms. From 2018 to 2020, nearly 1500 students contributed by sorting matrix into distinct categories: “plant”, “bone”, “shell”, and “other”. We evaluate the success of this project both in terms of producing usable scientific data and in its impact on the students. We found enjoyment was high among students who completed the ac- tivity. Overall, the level of accuracy of student work was less than that of trained volunteers. However, students were consistent in identifying fossils that were most likely to be valuable for research, and predictable errors provided insight into potential improvements. These data can inform planning for future research needs, lab workflows and opportunities for educational outreach at LBTP and other institutions worldwide.","PeriodicalId":203203,"journal":{"name":"Geological Curator","volume":"102 33","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138608047","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, fewer people are aware that fossils, ranging from fish to dinosaurs, and even coprolites can be radioactive too. A fossil may be radioactive if it has been exposed to uranium-bearing fluids during diagenesis and fossilisation processes. Any uranium-enriched groundwater moving through nearby porous deposit can contaminate the rocks and fossils with radioactive elements. Over time the skeletons or other remains being fossilised incorporate these elements into their min- eral structure, such that the concentration of radioactive elements in fossils may be greater than that in the host rock. The greater the volume of fossil material, e.g. a large dinosaur bone, the greater the potential for higher levels of radioactivity, and a greater risk to hu- mans (although some small specimens can be highly radioactive). Whilst most radioactive fossils may not present a danger to health through direct absorption of radiation, unless there is prolonged exposure at close quarters (e.g. hundreds of hours), a risk is posed by the ingestion or inhalation of small radioactive particles derived from the specimen. Here, we describe what measures can be taken to reduce these risks and also provide a list of locations around the world known to yield radioactive fossils, which we hope can be augmented by others. The general principles discussed here are widely applicable, but it is recommended that specialist advice is sought to comply with national regulations in each instance. In ad- dition to the health risks posed by these specimens, there are also legal penalties for failing to comply with regulations.","PeriodicalId":203203,"journal":{"name":"Geological Curator","volume":"144 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138989785","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}

Polly","doi":"10.55468/gc1460","DOIUrl":"https://doi.org/10.55468/gc1460","url":null,"abstract":"Grand Staircase–Escalante and Bears Ears are tracts of U.S. federal lands in Utah that were designated as national monuments in 1996 and 2016 respectively in part for the importance of their geological and palaeontological resources. In the 25 years since it was established, Grand Staircase–Escalante became known as the “science monument” for its strong emphasis on palaeontological science, including coordinating activities of its palaeontological manager. Synthesis of the hundreds of research papers there transformed scientific understanding of Mesozoic ecosystems. Before a management plan could be implemented at Bears Ears National Monument, President Donald Trump reduced the boundaries of both monuments to less than half their originally designated area. His action was arguably the first major rollback of palaeontological resources in the United States, underscoring the position of palaeontological science in the political debate about federal lands. Palaeontologists joined Native American tribes, conservation groups, and businesses in a joint effort to re-establish the monuments, an effort that was partially realised when President Joseph Biden restored their boundaries in 2021 but was not immediately able to reinstate previous management priorities. The palaeontological significance of these national monuments intersects with many other perspectives on the value and use of these lands, including indigenous and religious groups who faced oppression, the conservation of wilderness, economic and industrial development, and political struggle between state and federal, and executive and legislative aspects of government. This article explores the scientific significance and political context of the palaeontology of these two monuments as an example of how scientific priorities intersect with other societal pressures in the management of public lands.","PeriodicalId":203203,"journal":{"name":"Geological Curator","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127362937","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}

Wealthy private individuals who purchase expensive fossil specimens sometimes put them on public display but leave them in an intellectual limbo, unable to be studied and published. However, a partial T. rex skeleton known as Titus was excavated in Montana in 2018, shipped to the UK in 2020, and had casts of Stan's bones added to complete the skeleton during mounting. It was loaned to the Nottingham Natural History Museum, Wollaton Hall, as the centrepiece to a temporary exhibition called Titus: T. rex is King. This was the first time a mounted T. rex skeleton containing fossil bones had been on display in England for many decades. Importantly, before the mounting process began, all the real bones were 3D scanned in detail using photogrammetry. The resulting digital 3D models were sent to palaeontologists in America who studied them and produced a paper describing the palaeopathology before the mounting process was even complete. Replicas of all the identifiable bones were 3D printed for display in the exhibition and were accessioned into the museum collections, along with the 3D digital models and all associated data. This ensured that physical as well as digital replicas of the bones would remain accessible, and in theory publishable, forevermore.","PeriodicalId":203203,"journal":{"name":"Geological Curator","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125278669","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}
