Revision of Late Permian tetrapod tracks from the Dolomites (Trentino-Alto Adige, Italy)

<p>The Val Gardena Formation of the Dolomites region in northern Italy preserves the most significant assemblage of Late Permian tetrapod footprints in the world. More than 120 years of collecting resulted in about 900 publicly accessible specimens from the study area. This huge amount of data is comprehensively revised in the light of recent advances in the study of Late Palaeozoic – Early Mesozoic tetrapod ichnofossils. According to our analyses, the Val Gardena Sandstone Formation includes tracks that can be assigned to cf. <i>Batrachichnus</i> isp. (temnospondyl amphibian), <i>Capitosauroides</i> isp. (amphibian), <i>Dicynodontipus</i> isp. (cynodont therapsid), <i>Dolomitipes accordii</i> n. igen. n. comb. (dicynodont therapsid), cf. <i>Dromopus</i> isp. (neodiapsid), <i>Pachypes dolomiticus</i> (pareiasaurian parareptile), <i>Paradoxichnium problematicum</i> (archosauromorph neodiapsid), <i>Procolophonichnium tirolensis</i> n. comb. (procolophonoid parareptile), cf. <i>Protochirotherium</i> isp. (archosauriform neodiapsid) and <i>Rhynchosauroides pallinii</i> (neodiapsid). The ichnoassociation is dominated by tracks of neodiapsid and parareptilian tetrapods, whereas synapsid and anamniote tracks are rather minor components. It includes 10 out of 12 tetrapod ichnogenera known from Lopingian deposits and thus it constitutes a reference for the <i>Paradoxichnium</i> biochron. It shows striking similarities with other low-latitude non-aeolian contemporaneous ichnoassociations of Europe and North Africa, differences may be linked to the palaeoenvironment. Moreover, it shows a clear Triassic affinity.</p> <p>The new ichnogenus <i>Dolomitipes</i> was registered in Zoobank.org. urn:lsid:zoobank.org:act:5B4D871C-D16A-4E93-8211-CEE08019BA60</p>
