Abstract Documented here is a variation of the widely used resin transfer technique, allowing for the preparation of fragile articulated fossil arthropod material preserved in laminated limestone. The extensive use of the resin transfer technique in palaeontology has traditionally been restricted to palaeobotany and vertebrate palaeontology. The parameters discussed here allow for its application to three-dimensional arthropod fossils preserved in acid resistant minerals (e.g. iron oxides such as goethite, the sulphides pyrite and marcasite, and silica) in laminated limestone. In the experiments described here we have utilised fossils from the Lower Cretaceous (Aptian) Crato Lagerstatte of north-east Brazil. The equipment and methodology are outlined, along with cautions and concerns when using this technique.
