In the last decade, the first ichnoassamblages from the middle Muschelkalk facies (upper Anisian-middle Ladinian) of the Catalan Basin (NE Iberian Peninsula) have been discovered. Herein, the first xiphosuran trace fossils are described from the locality of Penya Rubí, a newly discovered ichnosite from the Catalan Basin. [...]

26 p, 2.5 MB Comments on Triassic Pterosaurs with a commentary on the "Ontogenetic Stages" of Kellner (2015) and the validity of Bergamodactylus wildi / Dalla Vecchia, Fabio (Institut Català de Paleontologia Miquel Crusafont)
Six stages (OS1-6) were identified by Kellner (2015) to establish the ontogeny of a given pterosaur fossil. 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. [...]

23 p, 14.3 MB Upper Paleozoic to Lower Mesozoic Tetrapod Ichnology Revisited : Photogrammetry and Relative Depth Pattern Inferences on Functional Prevalence of Autopodia / Mujal, Eudald (Institut Català de Paleontologia Miquel Crusafont) ; Marchetti, Lorenzo (Urweltmuseum Geoskop. Burg Lichtenberg) ; Schoch, Rainer R. (Staatliches Museum für Naturkunde Stuttgart) ; Fortuny Terricabras, Josep (Institut Català de Paleontologia Miquel Crusafont)
In recent years photogrammetry has become an essential tool in the study of tetrapod footprints. Morphological analyses of footprints are interpretative; thus, researchers should use as much information as possible in order to eventually provide an objective conclusion. [...]

13 p, 1.3 MB Clay mineralogy across the P-T boundary of the Xiakou section, China : Evidence of clay provenance and environment / Hong, Hanlie (China University of Geosciences. Faculty of Earth Sciences) ; Zhang, Ning (China University of Geosciences. Faculty of Earth Sciences) ; Zhaohui, Li (National Cheng Kung University. Department of Earth Sciences) ; Xue, Huijuang (China University of Geosciences. Faculty of Earth Sciences) ; Xia, Wenchen (China University of Geosciences. Faculty of Earth Sciences) ; Yu, Na (China University of Geosciences. Faculty of Earth Sciences)
The provenance of clays in shaley intervals across the Permian-Triassic boundary (PTB) in the Xiakou section was investigated by X-ray diffraction (XRD), differential scanning calorimetry (DSC), and scanning electron microscopy (SEM), and the results suggest that the layers have three different provenances. [...]

Departamento de Química Inorgánica, Cristalografía y Mineralogía) ; Franco, F. (Universidad de Málaga. Departamento de Química Inorgánica, Cristalografía y Mineralogía)
Diagenetic kaolin minerals are very common in the Permo-Triassic succession from the SE Iberian Range, Spain. The morphology and crystal structure of kaolin minerals has been examined in four size fractions (<1 μm, <2 μm, <6. [...]

12 p, 1.2 MB Volcanism in association with the prelude to mass extinction and environment change across the permian-triassic boundary (PTB), Southern China / Hong, Hanlie (China University of Geosciences. State Key Laboratory of Geological Process and Mineral Resources) ; Xie, Shucheng (China University of Geosciences. State Key Laboratory of Geological Process and Mineral Resources) ; Lai, Xulong (China University of Geosciences. State Key Laboratory of Geological Process and Mineral Resources)
In order to better understand the provenance of the sediments and environmental change associated with the Permian-Triassic (P/T) biotic crisis, a comparative clay mineralogical study of the Permian-Triassic boundary (PTB) sediments between the Meishan section (the Global Stratotype Section and Point of the PTB) and the Xiakou section, southern China, was undertaken using X-ray diffraction and differential scanning calorimetry (DSC).

24 p, 7.2 MB MORB-derived amphibolites in the Paleozoic basement of the Aluminé Igneous-Metamorphic Complex, Neuquén, Argentina : Decoding its genesis, P-T evolution and pre-Andean regional correlations / Urraza, Ivana A. (Universidad Nacional del Sur. Departamento de Geología) ; Delpino, Sergio H. (INGEOSUR (CONICET-UNS)) ; Grecco, Laura E. (Universidad Nacional del Sur. Departamento de Geología)
Amphibolites included in the metapelitic sequence and as xenoliths in intrusive magmatic rocks outcropping in the southern sector of the Aluminé Igneous-Metamorphic Complex (AIMC), Neuquén, Argentina, are studied in detail in order to determine their origin and their subsequent metamorphic evolution.

22 p, 1.8 MB New insights on the Permian and Triassic vertebrates from the Iberian Peninsula with emphasis on the Pyrenean and Catalonian basins / Fortuny Terricabras, Josep (Institut Català de Paleontologia Miquel Crusafont) ; Bolet, Arnau (Institut Català de Paleontologia Miquel Crusafont) ; Sellés, Albert G. (Institut Català de Paleontologia Miquel Crusafont) ; Galobart, Àngel (Institut Català de Paleontologia Miquel Crusafont) ; Cartanyà, Joan (Institut Català de Paleontologia Miquel Crusafont)
Few studies paid attention to the Permian and Triassic vertebrates from the Iberian Peninsula and a reevaluation of these faunas is needed in order to compare them with other European basins. As a first step, we present here the available data from the Catalonian and Pyrenean basins (NE of the Iberian Peninsula), offering new insights on the diversity and temporal distribution of their vertebrate faunas. [...]
Se han realizado hasta el momento pocos estudios de los vertebrados del Pérmico y el Triásico de la Península Ibérica y por este motivo, una re-evaluación de estas faunas es necesaria para compararlas con las halladas en otras cuencas europeas. [...]

The Triassic pterosaur Austriadactylus cristatus is reported for the first time from the Norian (Upper Triassic) of north-eastern Italy. It is only the second specimen of this taxon and provides new information on the mandibular dentition, cranium and postcranium (cervical vertebrae and the forelimb), not available in the holotype.
