ABSTRACT In 1934, Barnum Brown of the American Museum of Natural History in New York (AMNH) led a large-scale dinosaur excavation in northern Wyoming, where he had found bones two years earlier. Initially, Brown expected to excavate two skeletons of sauropod dinosaurs, but soon after opening the quarry, the team realized that the site far exceeded their expectations: in the end, they unearthed approximately 3000 bones within six months and sent approximately 144 crates back to the AMNH. Due to the enormous number of bones, the site became world famous as a dinosaur graveyard, and media from all over the United States and abroad reported on the expedition. Soon after, however, the collection shifted away from a curatorial focus. What followed was a history of neglect: inappropriate storage conditions, water and fire damage, collapsing wooden boxes, and deteriorating plaster jackets. Relocation and further excavation of the quarry by the Sauriermuseum Aathal (Switzerland; SMA) from 1989 to 1991 confirmed earlier finds of skin impressions and resulted in the recognition of a novel diplodocid sauropod: Kaatedocus siberi. Given that the amount of bones found by the AMNH far exceeded those found by the SMA, a new project was started in 2017 to reassess the state and scientific value of the historic collections at AMNH. Although most of the bones are heavily fragmented, preliminary results show that overall preservation is still exceptional. Here, we reconstruct the history of the excavation, as well as past conservation and preparation procedures, and provide a report of current efforts to prepare, conserve, and catalog the material that has remained in storage since the 1930s. These current efforts show that historic collections, even after decades of neglect, can be of great and unexpected value, both for research and scientific outreach.

重建豪采石场的标本和历史（上侏罗纪莫里森组；怀俄明州）

摘要 1934 年，纽约美国自然历史博物馆 (AMNH) 的巴纳姆·布朗 (Barnum Brown) 在怀俄明州北部领导了一次大规模的恐龙发掘，两年前他在那里发现了骨骼。最初，布朗希望挖掘出两具蜥脚类恐龙的骨骼，但在打开采石场后不久，该团队意识到该地点远远超出了他们的预期：最终，他们在六个月内出土了大约 3000 块骨头，并将大约 144 个板条箱送回了AMNH。由于骨骼数量庞大，该遗址成为世界著名的恐龙墓地，美国各地和国外的媒体都对这次探险进行了报道。然而，不久之后，该系列就从策展重点转移了。随之而来的是疏忽的历史：不当的储存条件、水火损坏、木箱倒塌、和不断恶化的石膏夹克。1989 年至 1991 年，Sauriermuseum Aathal（瑞士；SMA）对采石场的重新定位和进一步挖掘证实了早期发现的皮肤印痕，并导致了一种新型梁龙类蜥脚类恐龙的识别：Kaatedocus siberi。鉴于 AMNH 发现的骨骼数量远远超过 SMA 发现的数量，2017 年启动了一个新项目，以重新评估 AMNH 历史收藏的状态和科学价值。尽管大部分骨头都严重破碎，但初步结果表明，整体保存仍然很出色。在这里，我们重建了挖掘的历史，以及过去的保护和准备程序，并提供了一份关于准备、保护和编目自 1930 年代以来一直在储存的材料的当前努力的报告。
