Collection Improvement for O.C. Marsh's Dinosaurs at Yale/ Peabody Museum

这个项目涉及皮博迪自然历史博物馆的脊椎动物古生物学收藏。这些藏品的基础是19世纪末著名的“恐龙热潮”期间，奥斯尼尔·查尔斯·马什在美国西部收集的标本。保存在马什恐龙室的化石包括第一批被描述的著名和熟悉的恐龙标本，如迷惑龙（雷龙）、Barosaurus和剑龙。大约70年前，马什的恐龙被重新安置在耶鲁大学。这些骨头被存放在带有生锈金属格栅的开放式架子上。许多较大的骨头被储存在肮脏的、古老的黄麻填充的帆布垫上。露天储存使得所有的化石都被多年的灰尘和污垢所覆盖。由于没有充分的黄麻垫支撑，房间里几乎90%的大骨头都被自己的重量压碎了。还有许多由于旧粘合剂失效而破裂。在许多情况下，一个标本的不同部分被存放在房间的不同部分，这使得研究单个标本变得更加困难。在一个新的环境科学设施建成后，整个脊椎动物古生物学收藏品将被转移，该设施将容纳皮博迪博物馆的其他藏品。当这些藏品从Kline地质实验室的地下室移走后，脊椎动物古生物学收藏将扩展到环境控制的空间。该项目将在搬迁前对这些标本进行处理。虽然这些标本的状况本身就值得进行这项拟议的工程，但计划中的搬迁使得现在必须保护这些标本，因为在目前的情况下不可能安全移动它们。为改进这个集合所采取的步骤将包括：1。目前在开放式纸板托盘中的小样本和碎片将放置在聚乙烯泡沫衬里的托盘或聚丙烯容器中，用聚乙烯泡沫隔开以防止损坏。如有必要，聚乙烯泡沫支架将用于需要额外支持的较小样品。较长、较重的骨骼，如肢骨，将用聚乙烯泡沫衬里的石膏寝具支撑，而较小的骨骼，如椎骨，则用聚乙烯泡沫支撑。3. 易碎的纸张资料将被清洗并封装在聚酯薄膜中保存。所有可用的数据将被输入皮博迪博物馆的在线数据库。在研究蜥脚类恐龙和O.C.马什探险的专家约翰·麦金托什博士的帮助下，这些材料将被整理。地点和名称将在货架标签和计算机数据库中注明。这个项目涉及皮博迪自然历史博物馆的脊椎动物古生物学收藏。这些藏品的基础是19世纪末著名的“恐龙热潮”期间，奥斯尼尔·查尔斯·马什在美国西部收集的标本。保存在马什恐龙室的化石包括第一批被描述的著名和熟悉的恐龙标本，如迷惑龙（雷龙）、Barosaurus和剑龙。大约70年前，马什的恐龙被重新安置在耶鲁大学。这些骨头被存放在带有生锈金属格栅的开放式架子上。许多较大的骨头被储存在肮脏的、古老的黄麻填充的帆布垫上。露天储存使得所有的化石都被多年的灰尘和污垢所覆盖。由于没有充分的黄麻垫支撑，房间里几乎90%的大骨头都被自己的重量压碎了。还有许多由于旧粘合剂失效而破裂。在许多情况下，一个标本的不同部分被存放在房间的不同部分，这使得研究单个标本变得更加困难。在一个新的环境科学设施建成后，整个脊椎动物古生物学收藏品将被转移，该设施将容纳皮博迪博物馆的其他藏品。当这些藏品从Kline地质实验室的地下室移走后，脊椎动物古生物学收藏将扩展到环境控制的空间。该项目将在搬迁前对这些标本进行处理。虽然这些标本的状况本身就值得进行这项拟议的工程，但计划中的搬迁使得现在必须保护这些标本，因为在目前的情况下不可能安全移动它们。为改进这个集合所采取的步骤将包括：1。目前在开放式纸板托盘中的小样本和碎片将放置在聚乙烯泡沫衬里的托盘或聚丙烯容器中，用聚乙烯泡沫隔开以防止损坏。如有必要，聚乙烯泡沫支架将用于需要额外支持的较小样品。较长、较重的骨骼，如肢骨，将用聚乙烯泡沫衬里的石膏寝具支撑，而较小的骨骼，如椎骨，则用聚乙烯泡沫支撑。3. 易碎的纸张资料将被清洗并封装在聚酯薄膜中保存。所有可用的数据将被输入皮博迪博物馆的在线数据库。在研究蜥脚类恐龙和O.C.马什探险的专家约翰·麦金托什博士的帮助下，这些材料将被整理。地点和名称将在货架标签和计算机数据库中注明。

This project concerns the Vertebrate Paleontological Collections at the Peabody Museum of Natural History. The foundation of the collections are those specimens collected in the American West by Othniel Charles Marsh during the storied "dinosaur rush" of the late 19th century. The fossils stored in Marsh's Dinosaur Room include the first described specimens of such famous and familiar dinosaurs as Apatosaurus (Brontosaurus), Barosaurus and Stegosaurus. Marsh's dinosaurs were reposited at Yale approximately seventy years ago. The bones are stored on open racks with rusted metal grating shelves. Many of the larger bones are stored on dirty, ancient jute-filled canvas pads. The open storage has allowed all of the fossils to become covered with years of dust and grime. Inadequately supported by the jute-filled pads, virtually ninety percent of the larger bones in the room have broken under their own weight. Many others have broken due to the failure of old adhesives. In many cases, various parts of one specimen are stored in differing parts of the room, making it even more difficult to study a single specimen. The entire Vertebrate Paleontology collection is slated to move after the construction of a new environmental science facility that will house other Peabody Museum collections. When those collections are removed from the basement of Kline Geology Laboratory the Vertebrate Paleontology collection will expand into environmentally controlled spaces. The project will treat these specimens before the move. While the condition of the specimens alone merits the proposed project, the scheduled relocation makes it imperative to conserve the specimens now as it is impossible to safely move them in their current condition.The steps taken to improve this collection will include:1. Small specimens and fragments that are currently in open cardboard trays will be placed in polyethylene foam lined trays or polypropylene containers, separated by polyethylene foam to prevent damage. Where necessary, polyethylene foam mounts will be fabricated for smaller specimens in need of extra support.2. Longer, heavier bones, such as limb bones, will be supported with polyethylene foam lined plaster bedding jackets, and smaller bones, such as vertebrae, with polyethylene foam supports. 3. Fragile paper data will be cleaned and encapsulated in Mylar film to preserve it.4. All available data will be entered into the Peabody Museum's on-line data base.5. With the help of Dr. John McIntosh, an expert on both sauropod dinosaurs and the O.C. Marsh Expeditions, this material will be curated. Locations and names will be noted on both shelf labels and in the computerized database.This project concerns the Vertebrate Paleontological Collections at the Peabody Museum of Natural History.
