Anza palaeoichnological site, Late Cretaceous, Morocco. Part III: Comparison between traditional and photogrammetric records
11 pages; International audience; The present study evaluates a methodological workflow that could identify dinosaur tracks and trackways more comprehensively at outcrop scale. The approach described here is based both on 3D modelling by photogrammetry at different resolutions, and on suitably processed digital elevation models (DEMs). The ichnosite of Anza, Morocco, was chosen to demonstrate the efficiency of the proposed pipeline, because 323 dinosaur and pterosaur tracks discovered there have already been published. One subsector containing 89 tracks, identified in the two companion works that followed a traditional approach, was selected and divided into four subzones. By combining diff…
Paracamelichnum Jumillensisn.ichnogen. n.ichnosp., Upper Miocene Camelidae Ichnites from the Hoya de la Sima site (Murcia, Spain)
In the proximity of Jumilla (Murcia, Spain) there is a site called Hoya de la Sima with mammal footprints dating from the Upper Miocene. This site is an old gypsum quarry where footprints of Hipparion, Pecoripeda, Carnivora, Ursidae, and Proboscidea were discovered. While the site was being cleaned and conditioned after the discovery to protect the prints, Camelidae and other prints were unearthed and are currently being studied. The description of the Camelidae ichnites demonstrates that these belong to a new ichnogenera, produced by the prints of Paracamelus. The grouping of trackways is congruent with the gregariousness of these animals and with the concentration observed in similar site…
