Original Fossil, Cast or Reconstruction: How to Choose | 真化石、翻模复制与复原重构：怎么选

Three categories, three different claims

An original fossil is the specimen itself. A cast is a reproduction taken from a specimen or a licensed mould. A reconstruction is an interpretation that fills gaps with inferred anatomy. Each can be excellent, but they support different statements to visitors, insurers and researchers.

Originals: highest value, highest constraint

Originals carry scientific and emotional weight that nothing else matches. They also bring climate control, security, insurance and handling restrictions. Many institutions display originals in protected settings and use casts where visitors pass close or touch.

Casts: the working compromise

A well-made cast preserves surface detail and can be mounted, lit and shipped with far less risk. The quality question is not cast versus original but which mould and which finishing standard. Ask for the source specimen and the mould lineage; a cast of a cast degrades quickly.

Reconstructions: honest interpretation

Reconstructions are necessary where specimens are incomplete. The professional standard is to distinguish observed bone from inferred form, in the object itself or in accompanying interpretation. A reconstruction presented as a faithful specimen is a credibility problem waiting to surface.

How to decide

Start from the visitor experience and the risk tolerance. If close contact, touring or outdoor display is planned, casts and reconstructions usually carry the programme. If scholarly value is the point, protect the original and let the cast do the public work.

DinoCG supplies casts and reconstructions with documented provenance and clearly marked inferred sections, so exhibitions can describe what visitors are actually seeing.

三类对象，三种表述

真化石就是标本本身；翻模复制是从标本或授权模具翻制出来的复制品；复原重构则是用推断解剖补齐缺环的解释性作品。三者都可以做得很好，但它们对观众、保险方和研究者的表述是完全不同的。

真化石：价值最高，约束最多

真化石的科学与情感分量无可替代，代价是恒温恒湿、安保、保险和接触限制。很多机构的做法是把真化石放在受保护的位置展示，在观众近距离经过或可触摸的地方使用复制品。

翻模：务实的折中

做得好得翻模能保留表面细节，装架、布光和运输的风险都低得多。真正的问题不是翻模还是原件，而是用了哪副模具、达到什么表面标准。要问清来源标本和模具谱系，翻模的翻模会迅速损失细节。

复原：诚实的解释

标本不完整时，复原是必要的。专业标准是把观察到的骨骼和推断的形态区分开，无论在物件本身还是在解说中。把复原当作忠实标本展示，是一个迟早会被揭穿的信任问题。

怎么决定

从观众体验和风险容忍度出发。如果要近距离接触、巡展或户外展示，通常由复制品和复原承担主体。如果核心是学术价值，就保护原件，让复制品去做面向公众的那部分工作。

DinoCG 提供的复制与复原件带来源记录，并明确标注推断部分，方便展览如实说明观众看到的是什么。
