“…A three‐dimensional photogrammetric model of the specimen was made using a 24 Megapixel Canon EOS 750D (18 mm focal length). The software used to build a photogrammetric model is Agisoft PhotoScan Pro, already successfully applied both in the geological and palaeontological field (e.g., Breithaupt, Matthews, & Noble, ; Cipriani, Citton, Romano, & Fabbi, ; Citton et al, ; Citton, Nicolosi, Carluccio, & Nicosia, , Citton, Nicosia, Nicolosi, Carluccio, & Romano, ; Díaz‐Martínez, González, & De Valais, ; Fabbi, Romano, Citton, & Cipriani, ; Lomax, Falkingham, Schweigert, & Jiménez, ; Mallison & Wings, ; Pesci et al, ; Petti et al, ; Romano, Brocklehurst, & Fröbisch, ; Romano & Citton, ). A 3D PDF of the obtained model is provided in the Supplementary Information.…”

Here we describe a number of articulated teeth of a hybodont shark from Upper Jurassic deposits of the Monte Nerone Pelagic Carbonate Platform, in the Umbria‐Marche‐Sabina Palaeogeographic Domain (Northern Apennines, Central Italy). The material has been referred to as Asteracanthus cf. A. magnus, a quite well‐known taxon already reported from Middle to Upper Jurassic deposits of Europe. Teeth indicate an extreme crushing feeding behaviour, suggesting as putative prey both infaunal and epifaunal hard‐shelled invertebrates dwelling the sea‐floor, such as large bivalves, brachiopods, gastropods as well as vagile crustaceans. The finding represents, to date, the first formal report of hybodont shark in the Umbria‐Marche‐Sabina Domain, throwing further light on the ecology within Pelagic Carbonate Platform settings, and on the occurrence of Asteracanthus in the Late Jurassic of the Western Tethys.

“…This method, whose practice is explained by several papers (e.g., Falkingham, ; Mallison & Wings, ; Petti et al, ), enables preservation and communication more objectively about ichnological data. Its adoption has greatly increased in recent times, becoming almost a standard taking advantage of a protocol for ichnological studies (Falkingham et al, ) and being used as support of different approaches related to ichnological analysis (e.g., Castanera et al, ; Citton, Carluccio, Nicolosi, & Nicosia, ; Citton, Nicolosi, Carluccio, & Nicosia, ; Citton, Nicosia, Nicolosi, Carluccio, & Romano, ; Citton et al, ; Citton, Romano, Salvador, & Avanzini, ; Lallensack, Sander, Knötschke, & Wings, ; McCrea et al, ; Romano & Citton, ). High‐resolution Digital Photogrammetry is based on Structure from Motion (SfM) (Ullman, ) and Multi View Stereo (MVS; Seitz, Curless, Diebel, Scharstein, & Szeliski, ) algorithms and produces high‐quality dense point clouds.…”

The Torre del Porticciolo palaeontological locality (Alghero, north‐west Sardinia, Italy) is important for having provided the skeletal remains of the first Permian basal synapsid from Italy, Alierasaurus ronchii, the largest late early Permian to early middle Permian non‐therapsid synapsid known to date. Recently, other skeletal remains preliminarily attributed to a carnivorous non‐therapsid synapsid were described from a second site, approximately from the same stratigraphic level within the Cala del Vino Fm. During the excavation of this second site, tetrapod tracks were found near Cala Viola, about 1 km from the first two sites. The new find represents the first ichnological record from the Permian of Sardinia. The ichnological analysis allowed the recognition of tetrapods presently not recognized, just on the base of skeletal remains. This new evidence sheds more light on the faunal diversity within the Cala del Vino Fm., which is one of the few examples in the Permian of Europe of a combined ichno‐ and body‐fossil record. The tracks have been referred to as Merifontichnus, an ichnotaxon established from the uppermost portion of the Permian succession of the Lodève Basin in southern France. The new material is the first reliable occurrence of this ichnotaxon from Italy and would represent, to date, the oldest occurrence of the ichnogenus.

“…Therefore, 3D photogrammetry is the optimal tool for the preservation of such record. Recently, during fieldtrips to Tossal de Pollerini and Coll de Terrers sites (Mujal et al, 2017a,b) an unnamed aerial vehicle was used to take photos for the creation of high-resolution 3D photogrammetric models of: (1) the whole outcrops (Figure 6B) (for similar documentation of tracksites, see Citton et al, 2017;Romilio et al, 2017;Petti et al, 2018) and (2) relatively large (∼2-5 m 2 ) track-bearing surfaces (with sets of around 100 photos per surface) (Figure 6C). Besides providing new ichnological and sedimentological data (currently under analysis), these new models constitute a digital repository of this paleontological heritage.…”

In recent years photogrammetry has become an essential tool in the study of tetrapod footprints. Morphological analyses of footprints are interpretative; thus, researchers should use as much information as possible in order to eventually provide an objective conclusion. In this regard, photogrammetry is an extremely helpful tool to avoid potential biases and to better present ichnological data. We review the use of this technique in several Permian and Triassic tetrapod ichnological studies, with considerations on (1) ichnotaxonomy, (2) track-trackmaker correlation, (3) locomotion and/or behavior, (4) substrate induced effects, and (5) preservation of the fossil record and heritage. Furthermore, based on the available three-dimensional (3D) data on Permian and Triassic material, we present a first qualitative interpretation of relative depth patterns and the related functional prevalence (most deeply impressed area) within footprints. We identified three main groups: (1) anamniote, captorhinomorph/parareptile tracks (medialmedian functional prevalence), (2) diapsid tracks (median functional prevalence), and (3) synapsid tracks (median-lateral functional prevalence). The use of 3D photogrammetric models brings new light to the tetrapod footprint record, helping to better understand tetrapod communities throughout the late Paleozoic (and the end-Guadalupian and end-Permian extinctions) and the tetrapod recovery during the early Mesozoic.
