The Teruel Joint Paleontological Foundation-Dinópolis has developed an innovative methodology to enhance the visualization of dinosaur footprints in paleontological sites. This technique allows for improved interpretation and dissemination of fossil heritage without compromising its conservation or the scientific study of the footprints.
After conducting various tests in the laboratory and in the field, researchers determined that the most suitable solution consists of a mixture of oligomeric organosiloxanes dissolved in demineralized water and combined with powdered pigments, applied in layers with a brush. This technique is effective, reversible, and respectful of heritage. The applied product has hydrophobic properties that reduce the action of erosive agents such as runoff water, also acting as a protector of the fossils.
The process begins with outlining the contours of the footprints obtained through rigorous methodologies such as photogrammetry. Subsequently, the final product is applied with brushes onto the footprints.
Intervened Sites
The technique has been implemented in three specific sites in the province of Teruel: Aguilar 1 and Aguilar 3 in Aguilar del Alfambra, and Santa Ana in Ababuj. These sites have been recently opened for tourist visits as part of a cooperation agreement between the Teruel-Dinópolis Joint Paleontological Foundation and the Community of Teruel County, to develop the Dinoexperience Heritage Protection Plan.
The results obtained in these «in-situ museums» have allowed for increased visibility of the footprints among the general public, enhancing tourist appeal. It is anticipated that this methodology will continue to be developed in other dinosaur footprint sites in the province, including those that are part of «The Dinosaur Footprint Route».
Presentation and Funding
This research was presented by the team from the Dinópolis Foundation, led by Alberto Cobos, at the 40th Annual Meeting of the Spanish Paleontological Society held in Aracena (Huelva). The work is part of research funded by the Government of Aragon through the Department of Tourism and the FOCONTUR E04_23R Research Group, and by the Ministry of Science, Innovation, and Universities of the Government of Spain through the Paleontology Unit of Teruel and the PID2024-162804NB-I00 project.
