The Central Atlantic Magmatic Province (CAMP) has long been proposed as having a causal relationship with the end-Triassic extinction event (∼201.5 Ma). In North America and northern Africa, CAMP is preserved as multiple basaltic units interbedded with uppermost Triassic to lowermost Jurassic sediments. However, it has been unclear whether this apparent pulsing was a local feature, or if pulses...

The colossal size and body plan of sauropod dinosaurs are unparalleled in terrestrial vertebrates. However, to date, there have been only limited attempts to examine temporal and phylogenetic patterns in the sauropod bauplan. Here, we combine three-dimensional computational models with phylogenetic reconstructions to quantify the evolution of whole-body shape and body segment properties across ...

The classic Neotethyan Ankara Melange formed within the Triassic-Eocene İzmir-Ankara-Erzincan ocean (‘N Neotethys’), bordered in central Anatolia by Kırşehir and Tauride-Anatolide continental units to south discontinuous Sakarya continent northwest. Farther north, separate Intra-Pontide probably remained partly open until early Cenozoic. developed via phases of intra-oceanic accretion (mainly p...

Hydrocarbon generation in the Zechstein Main Dolomite and Upper Triassic potential source rocks of Polish Basin was investigated by 1-D thermal maturity modelling 90 boreholes across basin. This identified major zones potentially worthy further exploration efforts. The maximum burial depth reached >5 km during Late Cretaceous leading to organic matter. development reveals considerable differ...

Although often speculated, the link between Middle Triassic shoshonitic magmatism at NE margin of Adria plate and subduction-related metasomatism Southern Alps Sub-Continental Lithospheric Mantle (SCLM) has never been constrained. In this paper, a detailed geochemical petrological characterization lavas, dykes ultramafic cumulates belonging to magmatic event that shaped Dolomites (Southern Alps...

Stable carbon isotopic analyses of organic carbon (d13C) in individual paleosol profiles from Permian–Triassic sequences of Antarctica reveal systematic isotopic variations with profile depth. These variations are in many cases analogous to those in modern soils, which are functions of redox conditions, soil development, and degree and type of microbial decay. In modern soils, these isotopic de...

A new discovery of skeletons of Revueltosaurus callenderi from the Upper Triassic Chinle Formation of Petrified Forest National Park, Arizona clearly shows that Revueltosaurus is not an ornithischian dinosaur as previously supposed. Features such as the presence of a postfrontal, crocodile-normal ankle and paramedian osteoderms with anterior bars place R. callenderi within the Pseudosuchia, clo...

The Los Menucos Complex (North Patagonian Massif, Río Negro province, Argentina) has been long regarded as Late Triassic in age. A Dicynodontipus-dominated record is historically known from this complex and particularly the Puesto Tscherig locality. Here we report Vera site, where a new track-bearing horizon was discovered within 73-m-thick volcano-sedimentary succession. Footprints site are mo...

Microspores extracted from isolated sporophylls assigned to Lepacyclotes (syn. Annalepis) zeilleri the Ladinian (Middle Triassic) of northeastern France are described and studied in transmitted light as well with help scanning transmission electron microscopes. These spores, which monolete cavate, correspond Aratrisporites saturni if found sporae dispersae. Their ultrastructure is quite compara...
