New species of the rugose coral genus Lithostrotion Fleming in the upper Viséan from the Azrou-Khenifra Basin (Morocco)
2020
The new species Lithostrotion termieri Rodríguez & Somerville is described. It shows very large corallites of the rugose genus Lithostrotion Fleming. It has been recorded up to now only in upper Viséan rocks from the type locality, the Akrab ridge, Morocco also called Tizi Ben Zizouit by Termier & Termier (1950), who identified it as Lonsdaleia floriformis, and south-east from Tabainout, also from the Azrou-Khenifra Basin.
SIGNIFICANCE FOR INTERNATIONAL CORRELATION OF THE PERAPERTÚ FORMATION IN NORTHERN PALENCIA, CANTABRIAN MOUNTAINS. TECTONIC/STRATIGRAPHIC CONTEXT AND …
2021
Small ammonoid assemblages are recorded from the Perapertú Formation in northern Palencia. This is a mudstone unit with local platform limestones characterised by carbonate debris flows on the limestone margins. This unit, of Late Bashkirian to Early Moscovian age, participates in a series of southwards verging thrust slicesNorth of a major fault zone which originated as the head (leading edge) of a large thrust sheet with an internal deformation consisting of thrust slices and at least one nappe structure. Opposed vergencies at the head of this major thrust sheet (Carrionas Thrust Front) and the Ruesga Fault which locally modifies its trace, mark the position where the northern branch of t…
A catalogue of the vertebrate fossil record from the Guadix-Baza Basin (SE Spain)
2020
In this paper, a catalogue of the vertebrate content of the Guadix-Baza Basin is presented. A total of 93 localities have been reviewed, providing more than 300 vertebrate species. These localities have been included in 11 biochronological units, ranging in age from the late Miocene (MN 13) to the Middle Pleistocene (MmQ 4), including also two MN 10 localities. The best-represented epoch in the Guadix-Baza Basin is the Pliocene (MN 14 to MN 16), with 41 sites. This is followed by the Early Pleistocene (MN17 and MmQ1 to MmQ3) with 30 sites. The vertebrate classes represented in the basin are Actinopterygii, Amphibia, Aves, Reptilia and Mammalia, this last one being the best represented. Amon…

New skulls of the basal sauropodomorph Plateosaurus trossingensis from Frick, Switzerland: is there more than one species?
2021
The Triassic basal sauropodomorph Plateosaurus trossingensis is well-known from mass accumulations at the German localities of Trossingen and Halberstadt and the Swiss locality of Frick, and is significant especially regarding its ta-phonomy and proposed developmental plasticity. These implications, however, rely on the assumption that this material derives from a single species, which has been questioned. Here we describe new skull material from Frick including eight complete and six partial skulls, more than doubling the number of known skulls of P. trossingensis. This exceptional sample size allows for gaining a deeper understanding of variability that may occur in a single species. The …
Exploration of jet substructure using iterative declustering in pp and Pb–Pb collisions at LHC energies
2020
The ALICE collaboration at the CERN LHC reports novel measurements of jet substructure in pp collisions at $\sqrt{s}$= 7 TeV and central Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 2.76 TeV. Jet substructure of track-based jets is explored via iterative declustering and grooming techniques. We present the measurement of the momentum sharing of two-prong substructure exposed via grooming, the $z_{\rm{g}}$, and its dependence on the opening angle, in both pp and Pb-Pb collisions. We also present the first measurement of the distribution of the number of branches obtained in the iterative declustering of the jet, which is interpreted as the number of its hard splittings. In Pb-Pb collisions, we…
Calcareous nannofossil events in the Lower-Mildle Pleistocene transition at the Montalbano Jonico section and ODP site 964: Calibration with isotope …
2004
We present quantitative data on calcareous nannofossil biostratigraphy in the section of Montalbano Jonico (Southern Italy). This is one of the candidate Global Statotype Section and Point (GSSP) of the Middle Pleistocene. The first common occurrence (FCO) and last common occurrence (LCO) of Reticulofenestra asanoi are well detectable in the section and are here proposed as additional events for improving biostratigraphic resolution in the interval corresponding to the transition between the small Gephyrocapsa Zone and Pseudoemiliania lacunosa Zone. The potential value of the bioevents is tested in a Mediterranean deep-sea core of ODP Site 964, located in the Ionian Sea. At Site 964 the FCO…
Calcareous Nannofossil Biostratigraphy and Chronostratigraphy of ODP Hole 964D (eastern Mediterranean Sea)
2008
Quantitative analyses of calcareous nannofossil were carried out on sediments from ODP Hole 964D succession, recovered in the Ionian Sea, Eastern Mediterranean. Results show that the sedimentary sequence, spanning from about 3.5 Ma (Early Pliocene) to the Present, has been investigated through an average sampling resolution of less than 30 kyr. The detailed subdivision into 11 biozones makes it possible to recognize chronostratigraphic the boundaries in the Early Pliocene-Middle Pleistocene interval. Finally, two sedimentary gaps, lasting at least 340 kyr and 120 kyr respectively, have been recognized between the Zanclean and Piacenzian and in the lower part of the Early Pleistocene. SHORT …

Contribución al conocimiento de los moluscos del Pleistoceno Inferior del yacimiento de Barranco León (Cuenca de Guadix-Baza)
2020
Se exponen los resultados obtenidos en el análisis de la asociación malacológica de dos muestras pertenecientes a la capa D del yacimiento del pleistoceno inferior de Barranco León (Cuenca de Guadix-Baza). Los principales resultados obtenidos son la relación de especies que componen la asociación malacológica y su abundancia relativa, que indican su marcado carácter acuático. Por otra parte, pese a las limitaciones impuestas por la escasez de información tafonómica y la cautela que sugieren ciertos indicadores, se aporta, a partir del análisis de las exigencias ecológicas de cada taxón, una interpretación paleoambiental sobre las condiciones existentes en el momento del depósito. Éstas corr…
