This type of stemless crinoids has never previously been recorded in Italy, and this report bridges a significant gap. Morphofunctional analysis of the radial facets suggests that Tiburtocrinus toarcensis gen. et sp. nov. may have been a crawling paracomatulid, very different from other paracomatulids that probably swam.</jats:p>

These crinoids belong to the family Roveacrinidae and are characterised by their lacking a stem and free living above the sea floor. A new species, Roveacrinus derdereensis Manni, n. sp., has been erected.

The age of the fossil- bearing level is constrained between 488±2 and 457±4 ka based on the presence of well-dated volcanic ash layers at the top and at the bed of the diatomite level where the specimen was embedded. The fossil record of Caudata from the Pleistocene of central Italy is scarce, and this new find adds important data on the presence of the taxon in this area. The specimen, although comprised of a fairly complete and articulated skeleton, shows a sub-optimal preservation of single bony elements, to such an extent that a definite taxonomic assignment is not feasible. Moreover, it probably represents a juvenile individual in somatic terms at the time of the death. The specimen is tentatively referred to Triturus sp. RIASSUNTO - (Un salamandri...

All the sites discovered so far are characterized by dinosaur footprints and located in the Southern Alps (Northeastern Italy, Veneto, Trentino Alto-Adige) with the exception of the Mattinata tracksite (Southern Italy, Gargano Promontory, Apulia). The tracksites from the Southern Alps belong to four distinct stratigraphic horizons of the Lower Jurassic Calcari Grigi Group whereas the Mattinata track-bearing blocks are doubtfully assigned to the Upper Jurassic Sannicandro Formation (Kimmeridgian-Tithonian). For each site information is provided on the geographical and geological setting, age, ichnotaxonomy and possible trackmakers. The history of the discoveries, the evolution of the ichnological knowledge and the study techniques adopted through time are also described.

A careful analysis of previous studies indicates that the systematic arrangement of cyrtocrinids is very weak and unsatisfactory for several reasons. In particular, most of the original descriptions and diagnosis date from the past century and are logically influenced by a classical typological philosophy. Not being based on phylogeny, the currently accepted groups for cyrtocrinids must be putatively regarded as “artificial”. In addition, an inappropriate use of characters has been used, typically considered as diagnostic in other groups of crinoids but only marginally applicable to cyrtocrinids (the latter differently characterized for several highly distinctive and autapomorphic characters). In order to mitigate these problems and to arrive at the definition of characters and clades based on unambiguous synapomorphies, we present in this paper a preliminary and ...
