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

该项目涉及皮博迪自然历史博物馆的古脊椎动物收藏。 这些藏品的基础是19世纪世纪末著名的“恐龙热”期间由Othniel Charles Marsh在美国西部收集的标本。 存放在马什恐龙室的化石包括第一次描述的著名和熟悉的恐龙标本，如迷惑龙（雷龙），巴洛龙和剑龙。 马什的恐龙大约在70年前被安置在耶鲁大学。 骨头存放在敞开的架子上，架子上有生锈的金属格栅。 许多较大的骨头被存放在肮脏的，古老的黄麻填充帆布垫上。 露天存放使得所有的化石都被多年的灰尘和污垢所覆盖。 由于黄麻填充垫的支撑不足，房间里几乎90%的较大骨头在自身重量下断裂。 许多其他人已经打破了由于旧粘合剂的失败。 在许多情况下，一个标本的不同部分被储存在房间的不同部分，使得研究单个标本变得更加困难。 整个脊椎动物古生物学收藏品将在一个新的环境科学设施建成后搬迁，该设施将容纳皮博迪博物馆的其他收藏品。 当这些收藏品从克莱恩地质实验室的地下室移走时，脊椎动物古生物学收藏品将扩大到环境控制的空间。 该项目将在搬迁前对这些标本进行处理。 虽然标本的状况本身就值得进行拟议的项目，但预定的搬迁使得现在必须保护标本，因为在目前的状况下不可能安全地移动它们。为改善这一收藏所采取的步骤包括：1.将目前在开放纸板托盘中的小样本和碎片放入聚乙烯泡沫内衬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，将为需要额外支撑的较小样本制造聚乙烯泡沫支架。较长、较重的骨骼（如肢骨）将使用聚乙烯泡沫内衬石膏寝具护套进行支撑，较小的骨骼（如椎骨）将使用聚乙烯泡沫支撑。 3.易碎的纸质数据将被清洁并封装在Mylar薄膜中以保存它。所有可用的数据将输入皮博迪博物馆的在线数据库。在约翰·麦金托什博士的帮助下，他是蜥脚类恐龙和OC的专家。Marsh Expeditions，将对这些材料进行策划。 位置和名称将在货架标签和计算机数据库中注明。该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世纪世纪末著名的“恐龙热”期间由Othniel Charles Marsh在美国西部收集的标本。 存放在马什恐龙室的化石包括第一次描述的著名和熟悉的恐龙标本，如迷惑龙（雷龙），巴洛龙和剑龙。 马什的恐龙大约在70年前被安置在耶鲁大学。 骨头存放在敞开的架子上，架子上有生锈的金属格栅。 许多较大的骨头被存放在肮脏的，古老的黄麻填充帆布垫上。 露天存放使得所有的化石都被多年的灰尘和污垢所覆盖。 由于黄麻填充垫的支撑不足，房间里几乎90%的较大骨头在自身重量下断裂。 许多其他人已经打破了由于旧粘合剂的失败。 在许多情况下，一个标本的不同部分被储存在房间的不同部分，使得研究单个标本变得更加困难。 整个脊椎动物古生物学收藏品将在一个新的环境科学设施建成后搬迁，该设施将容纳皮博迪博物馆的其他收藏品。 当这些收藏品从克莱恩地质实验室的地下室移走时，脊椎动物古生物学收藏品将扩大到环境控制的空间。 该项目将在搬迁前对这些标本进行处理。 虽然标本本身的状况值得拟议的项目，预定的搬迁使得现在必须保护标本，因为不可能安全地移动它们在目前的状况。将目前在开放纸板托盘中的小样本和碎片放入聚乙烯泡沫内衬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，将为需要额外支撑的较小样本制造聚乙烯泡沫支架。较长、较重的骨骼（如肢骨）将使用聚乙烯泡沫内衬石膏寝具护套进行支撑，较小的骨骼（如椎骨）将使用聚乙烯泡沫支撑。 3.易碎的纸质数据将被清洁并封装在Mylar薄膜中以保存它。所有可用的数据将输入皮博迪博物馆的在线数据库。在约翰·麦金托什博士的帮助下，他是蜥脚类恐龙和OC的专家。Marsh Expeditions，将对这些材料进行策划。 地点和名称将在货架标签和计算机化数据库中注明。

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.
