Calcare di Altamura (Apulia)

The Calcare di Altamura (Italian for Altamura Limestone) is a Coniacian to early Campanian geologic formation in Italy. [1] The formation comprises limestones that are highly fractured, in places karstified and dolomitized. Fossil ankylosaur tracks have been reported from the formation. [2]

Description

The Calcare di Altamura overlies the Calcare di Bari, separated by an unconformity and is overlain by the Calcare di Caranna, separated by a transgressive angular unconformity. [3] [4] The Calcare di Altamura is subdivided into the Loferitique, Stromatolique and Gorjanovicia Members. [5] The formation comprises limestones with some levels of dolomitization. The succession starts with a sequence of stromatolites and is heavily fractured and karstified. [6] The formation crops out south of the Bari–Taranto railway. The lower part of the formation is dated to the Coniacian based on the presence of the microfossils Aeolisaccus kotori , Thaumatoporella parvovesiculifera , Accordiella conica and Moncharmontia appenninica . [7] The upper part is dated to the early Campanian. [5]

The Apulia Carbonate Platform in Apulia, Italy, was a major palaeogeographic element of the southern margin of the Mesozoic Tethys Ocean. It is one of the so-called peri-Adriatic platforms, which are comparable to the Bahama Banks in their carbonate facies, shape, size, and subsidence rate and, also, in the internal architecture.

The Altopiano delle Murge is a karst topographic plateau of rectangular shape in southern Italy. Most of it lies within Puglia and corresponds with the sub-region known as Murgia or Le Murge. The plateau lies mainly in the Metropolitan City of Bari and the province of Barletta-Andria-Trani, but extends into the provinces of Brindisi and Taranto to the south, and into Matera in Basilicata to the west. The name is believed to originate from the Latin: murex, meaning 'sharp stone'.

<span class="mw-page-title-main">Saltrio Formation</span>

The Saltrio Formation is a geological formation in Italy. It dates back to the Early Sinemurian, and would have represented a pelagic or near-epicontinental environment, judging by the presence of marine fauna such as the nautiloid Cenoceras. The Fossils of the Formation were described on the late 1880s and revised on 1960s, finding first marine biota, such as Crinoids, Bivalves and other fauna related to Epicontinental basin deposits.

The Isalo III Formation is a geological formation in Madagascar, off the eastern coast of Africa. It dates back to the Middle Jurassic. The use of the term "Isalo III" is somewhat controversial as the two prior units Isalo I and II are Triassic cross-bedded sandstone units that form a continuous depositional sequence, while the "Isalo III" sandstones are not part of the same depositional sequence, and were deposited considerably later. and are perhaps better treated as part of several separate formations. It is traditionally divided into two subunits the lower, Bajocian aged Isalo IIIa unit also known as the Beronono Formation and the upper, Bathonian aged Isalo IIIb unit also known as the Sakaraha Formation or Sakahara Formation. The Sakaraha Formation consists of sandstones, marls and carbonates and represents a coastal plain environment, and is laterally equivalent to the predominantly carbonate Bemaraha Formation, which represents a coastal barrier lagoon complex. The formation is found in the northwest and in the southeast of the country and has provided a variety of fossils.

<span class="mw-page-title-main">Timeline of ankylosaur research</span>

This timeline of ankylosaur research is a chronological listing of events in the history of paleontology focused on the ankylosaurs, quadrupedal herbivorous dinosaurs who were protected by a covering bony plates and spikes and sometimes by a clubbed tail. Although formally trained scientists did not begin documenting ankylosaur fossils until the early 19th century, Native Americans had a long history of contact with these remains, which were generally interpreted through a mythological lens. The Delaware people have stories about smoking the bones of ancient monsters in a magic ritual to have wishes granted and ankylosaur fossils are among the local fossils that may have been used like this. The Native Americans of the modern southwestern United States tell stories about an armored monster named Yeitso that may have been influenced by local ankylosaur fossils. Likewise, ankylosaur remains are among the dinosaur bones found along the Red Deer River of Alberta, Canada where the Piegan people believe that the Grandfather of the Buffalo once lived.

<span class="mw-page-title-main">Rotzo Formation</span> Jurassic geological formation in Italy

The Rotzo Formation is a geological formation in Italy, dating to roughly between 192 and 186 million years ago and covering the Pliensbachian stage of the Jurassic Period in the Mesozoic Era. Has been traditionally classified as a Sinemurian-Pliensbachian Formation, but a large and detailed dataset of isotopic 13C and 87Sr/86Sr data, estimated the Rotzo Formation to span only over the Early Pliensbachian, bracketed between the Jamesoni-Davoei biozones, marked in the Loppio Oolitic Limestone–Rotzo Fm contact by a carbon isotope excursion onset similar to the Sinemu-Pliens boundary event, while the other sequences fit with the a warm phase that lasts until the Davoei biozone. The Rotzo Formation represented the Carbonate Platform, being located over the Trento Platform and surrounded by the Massone Oolite, the Fanes Piccola Encrinite, the Lombadian Basin Medolo Group and Belluno Basin Soverzene Formation, and finally towards the south, deep water deposits of the Adriatic Basin. The also Pliensbachian Aganane Formation of Morocco represents a regional equivalent, both in deposition and faunal content.

The Calcare di Sogno is a geological formation in Italy, dated to roughly between 182-169 million years ago and covering the Lower Toarcian-Late Bajocian stagess of the Jurassic Period in the Mesozoic Era. Thallatosuchian remains are known from the formation, as well fishes and other taxa.

The Calcare di Bari is a Cretaceous geologic formation in Apulia, southeastern Italy. The formation comprises micritic limestones, in places karstified and dolomitized.
