The block was used to build the pier of Porto Corsini (Ravenna, Italy); the site of provenance is located on the southern flank of the Cansiglio Plateau (Pordenone, Northeastern ltaly) where there are several quarries. This is the first record of a dinosaur footprint in the Cretaceous of Italy and the first indication of Hauterivian dinosaur tracks in the Periadriatic carbonate platforms.

The preservation of the specimens does not allow a detailed taxonomic interpretation and for this reason they are referred to the lungfish suborder Ceratodontoidei, leaving indeterminate their familial and generic attribution. Dipnoans constitute an additional taxon to be added to the diverse vertebrate assemblage discovered in the Fusea site, formed by nothosauroids, cyamodontoid placodonts, the protorosaurian Tanystrophetis, small archosaurians, and elasmobranchian and actinopterygian fishes. These fishes provide evidence of freshwater influence in the sedimentary environment of this important paleontological site occuring at the boundary between two prevailing marine units (the Schlern/Sciliar Dolostone and the Val Degano Formation).

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...

Contrary to previous identifications, no footprints from the Neizar Valley belong to ornithopods; they can all be referred to theropod trackmakers. The Zerab footprint, on which the ichnospecies Iranosauripus zerabensis is based, is an undiagnostic theropod footprint and probably was lost. The skeletal remains are represented by bone fragments and a tooth of a mid-sized theropod, which represent the first dinosaur osteological record in this part of the Middle East. The Ab Bid Syncline has a high potential for further future discoveries.

Among the regions that stand out for the greatest gaps of knowledge regarding these flying reptiles, is the Afro-Arabian continent, which has yielded only a small number of very fragmentary and incomplete materials. Here we fill part of that gap and report on the most complete pterosaur recovered from this continent, more specifically from the Late Cretaceous (~95 mya) Hjoûla Lagerstätte of Lebanon. This deposit is known since the Middle Ages for the exquisitely preserved fishes and invertebrates, but not for tetrapods, which are exceedingly rare. Mimodactylus libanensis gen. et sp. nov. differs from the other Afro-Arabian pterosaur species named to date and is closely related to the Chinese species Haopterus gracilis, ...

These were used to support the erection of several new Triassic taxa including Bergamodactylus wildi, which is based on a single specimen (MPUM 6009) from the Norian of Lombardy, Italy. However, those ontogenetic stages are not valid because different pterosaur taxa had different tempos of skeletal development. Purported diagnostic characters of Bergamodactylus wildi are not autapomorphic or were incorrectly identified. Although minor differences do exist between MPUM 6009 and the holotype of Carniadactylus rosenfeldi, these do not warrant generic differentiation. Thus, MPUM 6009 is here retained within the taxon Carniadactylus rosenfeldi as proposed by Dalla Vecchia (2009a).
