In order to handle fossils for study and exhibition, a good state of conservation is paramount. In this work, the conservation operations carried out on a turtle fossil, described as Mauremys leprosa from the Pliocene site of Camp dels Ninots (Caldes de Malavella, Girona, Spain), are reported and documented. Cleaning, consolidation and preparation of the fossil was carried out, both on site and in laboratory. In particular, this work displays the interest of combining traditional conservation techniques with modern procedures such as 3D scanning. It is shown that the combination of 3D scanning and silicon moulding/casting can be extremely useful in order to document and preserve the anatomical connection of the fossils, especially when such fossils are embedded in fragile laminated or cracked sediment.
