The Quaternary deposits of the Oricola-Carsoli intermontane Basin (OCB) yielded an abundant but poorly studied vertebrate fauna (Fabbi et al., 2021). Hippopotamus cf. antiquus, Palaeoloxodon antiquus, and Stephanorhinus sp. remains were found in the 19th century in the municipalities of Vallinfreda and Riofreddo and described in early contributions...

“Classic” field mapping in sedimentary successions, where lithostratigraphy, biostratigraphy and sedimentology meet, still has potential for producing answers to long-standing problems in basin analysis. In the Northern Apennines of Italy, constraints on the slip rates of Early Jurassic rift faults, related to the embryonic separation of Eurasia an...

A review of the abundant vertebrate fauna found in the Quaternary deposits of the Oricola-Carsoli intermontane Basin is here presented, with a brief excursus on the history of the research in this area and some biochronological considerations on these faunal assemblages. Palaeoloxodon antiquus, Hippopotamus cf. antiquus, and Stephanorhinus sp. rema...

The Mesozoic of the Trieste Karst is part of the 90th Congress of the Italian Geological Society, Trieste Italy, 2021. The guide aims at documenting selected outcrops located on the Karst plateau where fossil richness is related to particular carbonate platform facies associations to highlight the area as an important archive for marine and contin...

The reconstruction of the hydrocarbon migration and entrapment history is fundamental for reducing risks and identifying traps and migration pathways during oil exploration and exploitation in fold-and-thrust belts, which host 14% of the world's discovered oil reserves. Within fold-and thrust belts, faults and folds have a fundamental role in contr...

We report a new coral assemblage collected from Kimmeridgian–Tithonian pelagic deposits of Northern Apennines. Such corals proliferate on intrabasinal structural highs (Pelagic Carbonate Platforms - PCPs) originated from dismembering and drowning of the vast Calcare Massiccio carbonate platform during the Early Jurassic Western Tethys rifting st...

Sclerobiont bryozoans have been found in the pelagic Maiolica Fm. of the Umbria-Marche Basin (Monte Acuto, Northern Apennines, Italy). The studied specimens, collected as loose material, are three sub-circular colonies of small size with tube-shaped zooecia, radially developing from the centre. Observable characters prevent generic or specific c...

In the present contribution we describe elasmobranch remains from the Aptian Albian Marne a Fucoidi cropping out at Mt Nerone (Umbria-Marche Ridge, Northern Apennines, Italy), representing the first occurrence of lamniform vertebrae from the Cretaceous of the Umbria-Marche Domain (Central Italy). Due to high fossilization potential of the hard dent...

The elasmobranch fossil record is essentially represented by isolated teeth due to high fossilization potential of hard dental components. Conversely, the cartilaginous skeletal elements, even though mineralized, are less prone to survive to the biostratinomic and diagenetic processes with negative implications in our understanding of the evolution...

We present the results of a geological mapping project performed in the southern portion of the Sibillini Mts., aimed at defining the structural relationships between the Sibillini Mts. Thrust front and the Mt. Vettore normal fault system, reactivated during the 2016-2017 central Italy seismic sequence. The Sibillini Mts. Thrust is characterised by...

The rudist-bearing carbonate platform succession of Marsia, in the northern Simbruini Mts. (Central Apennines), is described for the first time through the analysis of two stratigraphic sections, and better characterized by the study of three single significant outcrops located outside the sections. The identification of the rudist assemblages, rel...

The rudist fauna collected in western Tibet in the Aksai Chin area by the De Filippi expedition in 1914 has been reprised and redescribed. This fauna is composed of Radiolites cf. lusitanicus, Radiolites sp., Gorjanovicia cf. endrissi, ? Sauvagesia sp., Sphaerulites sp., Durania sp., and Gyropleura sp. The rudist-bearing beds belong to the Tielongt...

In the fall of 1894, an almost entire elephant skeleton was found in the municipality of Riofreddo (Rome) on the edge of the Piana del Cavaliere. The remains, in a poor state of conservation, were studied by Alessandro Portis, who identified the fossil species. Besides the elephant, Portis also studied the remains of hippopotamus, rhinoceros and a...

The asphalt mine of Filettino is located on the Simbruini Mts., near the sources of the River Aniene. The asphalt in the area was discovered in the 18th century and described for the first time by B. Gandolfi in 1789. Bitumen impregnates the Triassic dolostones that crop out extensively in the area; its occurrence is favored by the intense fracturi...

The Subiaco Stone is a high quality and very versatile lithoid material extracted in an abandoned quarrying near the town of Subiaco (Rome Province - Italy). The quarry activity was very discontinuous but, despite this, the material was appreciated in Italy and abroad as it was used to build monuments since the 18th century to the ’30s of the 20th...

The Collepardo cave is a karst hole, located south of the Collepardo village (Frosinone province), in the canyon of the Fiume creek, tributary of the Cosa river. It is caved in strongly fractured Cretaceous limestone, separated from Jur-assic and Miocene carbonates through tectonic lineaments. The cave mouth is roughly triangular, with maximum widt...

Here we report newly collected corals from Kim-meridgian-Tithonian pelagites of Central and Northern Apennines. They grew on intrabasinal structural highs (Pelagic Carbonate Platforms or PCPs). The highs originated from dismembering and drowning of a vast peritidal carbonate platform during the Early Jurassic Western Tethys rifting stage. The drown...

The Mt Nerone area hosts a Jurassic-Cretaceous Pelagic Carbonate Platform (PCP)-basin succession in the Umbria-Marche Domain (Central Italy). Despite being studied thoroughly on sedimentological and geological aspects, wide-spectrum palaeocological studies are currently missing for this peculiar setting. While several studies on the invertebrate fa...

In the Late Jurassic and Cretaceous the warm shallow water seas were marked, within benthic marine organisms, by rudist bivalves, a peculiar group of mollusks that originated in the Late Jurassic and became extinct at the end of the Cretaceous. In this paper their global distribution in neritic carbonates is considered since their first appearance...

We describe the first evidence of sclerobiont bryozoans found loose in the pelagic Maiolica Fm. of the Umbria-Marche Basin (Monte Acuto Massif, Northern Apennines, Italy). The material is represented by three small sub-circular colonies with tube-shaped zooecia radially developing from the centre. These characters are not enough for generic or spec...

years 1913-1914 through the Himalayan Range from Kashmir to Baltistan and Xinjiang (then part of the British Empire and China, today belonging to China, Pakistan and India), part of the expedition crossed the remote region of the Aksai Chin with high mountains and highlands more than 5000 meters. Members of the mission were, along with the leader F...

In the late Jurassic and Cretaceous the shallow and warm water seas were marked, among other benthic marine organisms, by rudist bivalves, a peculiar group of fossils that originate in the late Jurassic and became exinct at the end of the Cretaceous. Rudist occurrences reported in three publicly available databases (Paleotax, PaleobioDB and Paleo-r...

In the last decades, methodologies for three-dimensional digitisation of geological outcrops have considerably grown. These methods provide to geologists powerful tools to collect, manipulate and communicate field evidence through the reconstruction of high-resolution digital models, starting from a considerable amount of raw data. Among the differ...

The Mt Nerone Pelagic Carbonate Platform is proving to be a feasible observatory for a more inclusive understanding of the vertebrate/invertebrate palaeocommunities that inhabited the Jurassic sea of the Umbria-Marche-Sabina Domain. While the invertebrate fauna from Mt Nerone area has been largely studied in the past, formal descriptions of the ver...

A coral interpreted as a shallow-water zooxanthellate (z-) form has been recovered from the uppermost part of a condensed, pelagic carbonate platform-top succession, in levels with transitional characters between the Jurassic Bugarone Group and the Maiolica Formation, a calpionellid-bearing pelagic deposit. While the existence of z-corals in the Ju...

Five Upper Cretaceous stratigraphic sections have been measured and sampled in the tectonically complex area of Marsia (northern Simbruini Mts.), allowing the reconstruction of a ~60 m thick inner carbonate platform succession.

Tethyan Pliensbachian carbonate platforms share many features in terms of biota, like the presence of a Lithiotis fauna, green algae and benthic forams associations. A carbonate platform is influenced, among other factors, by its position within a sedimentary basin, the inherited substrate, and the local trophic conditions. The carbonate factories...

We combined structural and stratigraphic methods to highlight the deep structure along the axial sector (Middle Val Roveto) of the central Apennines fold-thrust belt, where no seismic reflection profiles or boreholes are available, despite the occurrence of major thrust fronts (i.e., the Simbruini-Ernici and Vallelonga thrust fronts) and one of the...

By the early nineteenth century, the peiagic carbonate piatform (PCP) of Mt. Nerone in the UmbriaMarche Sabina (UMS) Domain (Umbria-Marche Apennine, Itaiy) attracted schoiars from all over Europe due to the wealth of fossil fauna preserved in a stunningiy well-exposed Mesozoic sedimentary succession.

A unique f...

The upper Miocene dominantly terrigenous succession cropping out at Monte San Fabrizio (Simbruini Mts.) shows peculiar, previously unreported bio‐sedimentological features, which bring fresh elements in a regional palaeogeographic/palaeotectonic key. Overlying the regional foredeep succession, an array of different lithofacies either form mappable...

The Umbria-Marche-Sabina (hereafter UMS) Domain in Central and Northern Apennines hosts a Upper Triassic to Neogene sedimentary succession recording a rifting stage occurred by the late Hettangian, dismembering a Bahamian-type carbonate platform. Tectonic subsidence and palaeoceanographic/palaeoecological perturbations diachronically led to the dro...

The carbonate succession cropping out in the Upper Aniene Valley was studied since the last decade of the XIX century. Before, only generic mentions to the fossil content of carbonate rocks were made. Since the year 1890 the interest of geologists for this part of Italy grew up, mostly due to the finding of an abundant rudist fauna from the Monte A...

It is a widely diffused opinion that the knowledge of the geologic features of the Calabrian territory may be referred to the early XX century; nevertheless, a thorough investigation carried out in the cartographic collection of the ISPRA Library, that preserves the historical heritage of the Geological Survey of Italy, allowed to access and analyz...

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 Midd...

In this contribution we present the first material referable to hybodont shark from the Rosso Ammonitico Formation (Umbria-Marche-Sabina Palaeogeographic Domain). Two teeth were recovered isolated within Toarcian red marly-limestone (Bifrons Zone). The best-preserved tooth is characterized by a general structure well in accord with the classic crus...

Celebrating the centennial of Domenico Lovisato's death (1842-1916), this paper highlights the role played by this eminent Italian geologist as a pioneer for the geological knowledge of Calabria region (Southern Italy), a geologically complex area which became the subject of a long-lasting and still continuing debate. Lovisato spent only few years...

In their paper on the Montagna dei Fiori area, Storti et alii (2017) present a new geological map and discuss the dolomitization pattern and the Jurassic extensional architecture of this sector of the Central Apennines. They conclude that their "field evidence does not support the gravity-driven olistolith hypothesis proposed by Di Francesco et ali...

I Monti Simbruini e gli Affilani sono due dorsali carbonatiche separate dalla valle dell'Aniene, la cui stratigrafia consta essenzialmente di una potente successione di piattaforma carbonatica di età compresa tra il Triassico superiore e il Miocene medio, con un importante hiatus tra il Cretaceo superiore e il Miocene inferiore. La porzione cretaci...

La presente ricerca sull'evoluzione della conoscenza geologico/paleontologica del Mesozoico della Valle dell'Aniene, a cavallo tra il XIX e il XX secolo, si inquadra nell'ambito di un più ampio progetto rivolto alla revisione di alcuni taxa di rudiste aventi alto significato biostratigrafico e storico, e in particolare, ad oltre un secolo dalla sua...

In the northern Simbruini Mts. (Oricola-Rocca di Botte area, AQ) of Central Italy, the Neogene terrigenous stratigraphy represents a geological unicum in the region, with features described here for the first time. Overlying the Bryozoan limestone, the "Orbulina marls" pass upwards to a marl/sandstone alternation ascribable to the apenninic foredee...

The early geological studies of Libya were carried out by Rolland (1880) who made the first geological map. Nevertheless, Italian geologists have conducted pioneering studies, and accurately described the stratigraphical architecture of the country. Taramelli and Bellio (1890) published a volume devoted to the geography and geology of Africa, in wh...

Re-sedimented deposits characterize different stratigraphical intervals in the pelagic successions of the Umbria-Marche-Sabina Domain (Central and Northern Apennines, Italy). Three stratigraphic sections of the Maiolica and Marne a Fucoidi Formations, characterized by breccias and calcarenites embedded in pelagic sediments, were sampled across the...

The sedimentary successions exposed in northeast Calabria document the Jurassic-Early Cretaceous tectonic-sedimentary evolution of a former segment of the European-Iberian continental margin. They are juxtaposed today to units representing the deformation of the African and Adriatic plates margins as a product of Apenninic crustal shortening. A com...
