一具名为“Jodi”的稀有纳米暴龙（Nanotyrannus）完整骨架在纽约苏富比拍卖行以4730万美元的价格落槌，成为史上第二昂贵的恐龙化石1。这场激烈的竞拍仅持续了12分钟，最终由6名竞标者中的一人胜出，成交价远超苏富比此前预估的600万至900万美元区间1。这具发现于美国蒙大拿州加菲尔德县地狱溪组（Hell Creek Formation）的化石由Jodi Pierson于2019年发掘出土，是已知现存仅有的三具完整纳米暴龙骨架之一1。该标本生存于约6700万年前的白垩纪晚期，全长19.6英尺、高约9.6英尺，包含约191块骨骼元素1。
此次高价交易引发了部分科学家对公共科研资源流失的担忧。马里兰大学专家Thomas R Holtz Jr指出，鉴于博物馆正面临预算削减甚至关闭的风险，单具化石的实际成本远低于此次拍卖价格，巨额资金若用于支持博物馆运营将更具公益价值1。Syracuse大学教授Linda Ivany也强调，此类重要标本应留在公共领域，以便供科学研究和教育使用，而非流入私人收藏导致其脱离公众视野1。
A rare skeleton of the dinosaur genus Nanotyrannus, named "Jodi," sold for $47.3 million at a Sotheby's auction in New York, establishing itself as one of the most expensive fossils ever recorded 1. The specimen is one of only three known complete Nanotyrannus skeletons and measures 19.6 feet in length with a height of approximately 9.6 feet, comprising about 191 bone elements 1. Originating from the late Cretaceous period roughly 67 million years ago, the fossil was discovered by Jodi Pierson in 2019 within the Hell Creek Formation in Garfield County, Montana 1.
The sale concluded after just 12 minutes with six bidders participating, significantly exceeding Sotheby's initial estimate of between $6 million and $9 million 1. This transaction marks the fossil as the second most expensive dinosaur skeleton in history 1. However, the high price point has drawn criticism from some scientists who argue that such significant specimens risk disappearing into private collections rather than remaining accessible for public research and education 1. Linda Ivany, a professor at Syracuse University, advocates for keeping fossils in the public domain to support scientific study and educational purposes 1.
Concerns also extend to museum funding issues, with Thomas R Holtz Jr., an expert from the University of Maryland, noting that many museums face closure risks due to budget cuts while the cost of maintaining a single fossil remains far below its auction value 1. Critics suggest that funds generated from such sales could be more beneficial if directed toward supporting museum operations, ensuring broader public access to natural history resources 1.
