They are located in the upper part of the Rotzo Formation (Lower Jurassic). An excellent preservation state of the specimens, the darkness and scarce re-crystallisation of the matrix, and the broad lateral extension of the mounds allowed us a reliable taxonomic classification and the reconstruction of bank geometries.

The tracks occur in mixed carbonate siliciclastic basal levels of the Illyrian Calcare di Morbiac Fm. The tracks represent a typical Anisian Alpine ichnoassociation in which have been identified Rhynchosauroides tirolicus, Chirotherium barthii, Isochirotherium delicatum, Brachychirotherium isp. RIASSUNTO-Un nuovo icnosito a vertebrati dell'Anisico superiore (Illirico) delle Dolomiti (Italia settentrionale)-Viene descritto un nuovo icnosito identificato nelle Dolomiti Centrali. Le tracce fossili sono conservate all'interno di alcuni livelli silicoclastici alla base del Calcare di Morbiac (Illirico). Le tracce corrispondono ad una tipica icnoassociazione dell'Anisico delle Alpi nella quale sono stati riconosciuti Rhynchosauroides tirolicus, Chirotherium barthii, Isochirotherium delicatum, Brachychirotherium isp.

The Southern Alps of Italy (SA) show a number of very thick and well-exposed successions and preserve one of the best tetrapod footprint records of this time interval, either for the abundance, quality and diversity of the ichnoassociations. Furthermore, the stratigraphy of this area is well-constrained by radiometric datings, microfloras from both continental and marine units, invertebrate fossils and microfossils, sequence stratigraphy, carbon stable isotopic stratigraphy and magnetostratigraphy from interspaced marine units (Fig. 1). We revised the stratigraphic record of tetrapod footprints of this area, updating existing ichnofaunal units (IFUs) and describing ichnoassociations that may represent IFUs. IFUs are informal ichnoassemblages of possible biostratigraphic value (conti et al., 1997; avanzini et al., 2001a). IFUs and ichnoassociations have been correlated with tetrapod footprint biochrons as listed in the following. A) The oldest tetrapod footprint record in the SA occurs in the latest Carboniferous (Ghzelian) continental Corona Formation (Carnic Alps), which yielded probable anamniote tracks (Mietto et al., 1986). This record is considered too small to represent a proper IFU. B) The first extensive ichnoassociation is from the Lower Permian (Kungurian) continental Collio, Dosso dei Galli, Pizzo del Diavolo, Monte Luco and Tregiovo formations, all well-constrained by radioisotopic methods (e.g., schaltegger & brack, 2007; Marocchi et al., 2008). It is characterized by common non-archosauromorph eureptile and parareptile tracks, anamniote tracks and rare synapsid tracks (e.g.,

Most ichnosites are located in the Southern Alps but track-bearing localities are also described in the Western Alps and in Northern Apennines. The stratigraphic distribution of tetrapod footprints can be framed in two macro-sets. A first set ranges from the late Early Triassic (Olenekian) to the Middle Triassic (Late Anisian, Illyrian) where ichnoassociations are dominated by lizard-like footprints (e.g. Rhynchosauroides isp.) with gradual increase through time of footprints referable to crurotarsal archosaurs (e.g. chirotheriids). After a hiatus ranging up to the basal part of the Carnian (basal Julian), a second set of ichnoassociations spreads the whole Late Triassic. This second set is dominated by crurotarsal footprints from its base but, in correspondence with the abrupt global climate of the...

Revision of paleontological data on Ursus spelaeus occupation of the cave and new data coming from a test excavation made in the “Sala dei Misteri” are here presented together with the preliminary results of radiometric dates performed on bear bones and charcoals. The integrated interpretation of recent archaeological data and palaeosurfaces laser scans, along with geoarchaeological, sedimentological, geochemical and archaeobotanical analyses, geometric morphometrics and digital photogrammetry of human footprints, enabled us to reconstruct the activities that an Upper Palaeolithic human group led inside a deep cave in northern Italy within a single exploration event dating about 14 ky cal BP. A complex and diverse track records of humans and other animals shed light on individual and group level behaviour, social relationship, and mode of exploration of the uneven terrain at the end of the Upper Palaeolithic. A group of five individuals, composed of two adults, an adolescent and two children, entered the cave barefoot lightening the way with a bunch of wooden sticks (Pinus t. sylvestris/mugo bundles) apparently for a single exploration episode, despite the fact that they left several traces of possible symbolic behaviour that will be the subject of future research projects.

Sporadic findings confirm the presence of sheep shepherds between the 2nd and 5th centuries. More abundant archaeological materials reveal a widespread exploitation throughout the subsequent medieval period up to the 11th century, indeed. In this phase the first buildings appear: small constructions at the top of reliefs with 360-degree panoramic views and near water sources. Between the 11th and 13th centuries, the lack of archaeological evidence suggests a stasis in the mountain frequentation. Traces of material culture and documentary attestations reappear starting from the mid-fourteenth century. The buildings of this phase are similar to the previous ones and distinguishable only by their larger size. During the seventeenth century there was a shift from sheep to cattle breeding with a change in the logistic system of the summer farms. The multifunctional building, which for centuries had been the only pole of the pastures, is splitted into two buildings: the dairy, where the milk is processed, and the warehouse, where the dairy products are kept. This organization continued unchanged until the beginning of the twentieth century.

A revision work on the entire collections revealed the presence of Hyloidichnus bifurcatus Gilmore, 1927 and Limnopus heterodactylus (King, 1845). The ichnoassociation now lists seven ichnogenera: Amphisauropus, Batrachichnus, Dromopus, Erpetopus, Hyloidichnus, Limnopus, Varanopus. These new data enlarge the ichnoceonosis, adding tracks of medium-size captorhinomorphs (Hyloidichnus) and temnospondyls (Limnopus) to the Italian ichnofauna, previously characterized by scarcity of predators and amphibians. Radiometric ages give a strong age constraint to the ichnoassociation (Early Kungurian), allowing useful correlations to contemporary successions all over theworld. Themain difference is the absence of Ichniotherium andDimetropus, and this could have a stratigraphic or paleoenvironmental significance. The fauna is similar in two main basins, Collio and Orobic. It differs solely in the proportions between ichnotaxa, with a predominance of areoscelid traces (Dromopus) in the Collio Basin and of captorhinomorph traces (Erpetopus, Varanopus, Hyloidichnus) in the Orobic Basin. This datum could reflect slightly different environments, seasonal in the Collio Basin (alluvial plain) and more arid in the Orobic Basin (playa-like). The lack of some forms in smaller basins of the Athesian Volcanic Complex is probably due to a bias.

Palaeoenvironmental indications given by the presence of this trace fossil are added to the stratigraphical and sedimentological data for the Coste dell'Anglone dinosaur ichnosite.

Le indicazioni paleoambientali fornite dalla presenza di questa traccia vengono integrate ai dati stratigrafici e sedimentologici noti per l'icnosito ad orme di dinosauro di Coste dell'Anglone.

Tale presenza sarebbe stata necessaria per garantire la sussistenza delle popolazioni stanziali di dinosauri documentate nei depositi immediatamente soprastanti a quelli descritti.
