Geothematic map of the Lavini di Marco tracksite (Lower Jurassic, NE Italy, Southern Alps)

A new ichnological study was carried out on the dinosaur tracks from the Lavini di Marco ichnosite (Trentino-Alto Adige/Südtirol, NE Italy), on the framework of a joint project between the Sapienza University of Rome and the MUSE - Sciences Museum of Trento, withthe cooperation of the Geological Survey and the Fire Department of the Autonomous Province of Trento. The project consisted of anew analysis, made possible through modern digital technologies, of the Lower Jurassic tracks attributed to theropod and sauropoddinosaurs. Additionally, it included the realization of a geothematic map of the entire site, representing the objective of this contribution.Two different approaches were used during the ichnological mapping: i) traditional methods and ii) aerial- and close-range photogrammetry. Aerial photogrammetry was performed using two distinct drones, obtaining orthophotos and orthoplanes of the tracks-bearing horizons, to produce a detailed geothematic map. Close-range photogrammetry led to the production of more than seventy 3D color-coded models of the best-preserved dinosaur footprints.The map was produced in digital vector format with different levels of knowledge. The final geothematic map represents a completemultilayer documentation that will be useful for future work of conservation, dissemination, and valorization of the tracksite.
