Dinosaur Footprints in Terrigenous Sediments on the Early Jurassic Shelf of the Central North Caucasus: Sedimentological and Paleoecological Settings.

Dinosaur footprints were found in Pliensbachian terrigenous rocks in the central North Caucasus. Tracks of different sizes (12-35 cm) were identified at three levels of the Mizur Formation section. The sediments accumulated on the wide (15-20 km) shelf of a paleobasin. The coastal land was covered with abundant vegetation. The warm and humid climate favored the development of weathering crusts, lake-bog systems, and peat accumulation. The seawater temperature ranged from 21 to 25ÂC. The accumulation of sediments on the shallow shelf and their distribution over the area were influenced by wave activity, currents, and tidal phenomena. At low tide, small dinosaurs visited the shelf zone in order to search for food in the form of benthic fauna, which was abundant in clayey-silty sediments. The simultaneous presence of significantly differentâsize animal tracks may indicate that large individuals preyed on smaller ones. The presence of dinosaur tracks at different levels of the upper Pliensbachian strata indicates that representatives of the terrestrial fauna periodically visited the paleoshelf during the Domerian.

Multiscale geometric 3D recording of palaeontological heritage in La Rioja (Spain): regional context, sites, tracks and individual fossils.
Journal of Iberian Geology (advance online publication)

The region of La Rioja (Spain) is rich in paleontological sites, especially those related to dinosaur fossil footprints, of which more than 150 tracksites with more than 10,000 tracks have been described. The cataloging and systematic study of this heritage requires its correct location in space and the provision of an adequate geometric representation of both the distribution of remains in the sites and the three-dimensional shape of the different fossil elements. In this work, the various geometric documentation techniques used for this purpose (GNSS, photogrammetry and structured light scanner) are presented, as well as the description of the main products that are generated and their usefulness for the study, management, outreach activities and preservation of paleontological heritage in this region. These products will be key to the development of paleontological research projects and the development of educational and outreach tools.
