The development of “modern” palaeontological laboratory methods: a century of progress

Vertebrate fossils have been converted from natural history objects into research specimens through the act of preparation for over 200 years. All of the basic techniques applied to specimens in the 21st Century were already in use in palaeontological laboratories by the first decade of the 1900s. It behoves any worker in the field to be intimately familiar with processes for treatment of specimens, as these procedures almost always permanently alter material available for interpretation. Historic treatments also complicate attempts to re-treat or re-prepare specimens. Sometimes this results in damage to fossils and loss of information, and often in wasted resources. Most palaeontologists are unaware of the historical evolution of laboratory methods through this time; much of the documentation of this process is considered to be obscure. However, there is in fact a robust body of literature that chronicles the development of procedures for the preparation of fossils. Awareness of the past development of methods is crucial to guiding future directions in the palaeontological laboratory. Regular reporting of laboratory methods in the technical literature at a pace matching that of other analytical methods is integral to the function of palaeontology as a science.
