The palaeontological heritage of Majorca is subject to constant threats that could lead to its progressive disappearance. A methodological proposal is presented in order to facilitate its conservation and management, which consists of defining, cataloguing, characterizing and evaluating the palaeontological heritage, in the most objective and justified way possible, based on a clear definition of the heritage studied (sites of paleontological interest); an exhaustive and methodical process of cataloguing, using predetermined criteria; a clear and concise characterization appropriate to the elements studied (stratigraphy, faunal singularity, extension, thickness, conservation, etc.); and an evaluation with predetermined and justified criteria, based on the cataloguing and characterization carried out. Palaeontological sites, often the most significant, useful or vulnerable sites, are thus selected, and strategies for management and conservation (protection, surveillance, cleaning, study, centres of interpretation, etc.) proposed that are appropriate for each site. The proposed methodology is intended to be scientific and extrapolable to other studies and heritage elements.
