Temporal and phylogenetic evolution of the sauropod dinosaur body plan [PDF]

, 2016
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.

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

Geological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Late Permian/Early Triassic stress events and Permian–Triassic boundary in Croatia

Mémoires de Géologie (Lausanne), 2023
Upper Permian and Lower Triassic deposits are one of the best studied on our planet, and various scientists, by studying these deposits and by determining the Permian–Triassic Boundary (PTB), try to resolve the cause of the biggest mass extinction in the geological history. Several studies in Croatia focused on these, rarely exposed deposits.

Morphology and osteo‐histology of the weigeltisaurid wing: Implications for aerial locomotion in the world's first gliding reptiles

Journal of Anatomy, EarlyView.
This study investigates the morphology and osteo‐histology of the wing skeleton of the world's first gliding reptiles, showing how it differs from those of extant gliding lizards, yet is also convergently similar. These findings pave the way for future biomechanical studies on the gliding locomotion of these emblematic fossil animals. Abstract The Late

BIOMECHANICAL FRAGMENTATION IN SHELL-BEDS FROM THE LATE TRIASSIC OF THE LOMBARDIAN BASIN (NORTHERN ITALY). PRELIMINARY REPORT

Rivista Italiana di Paleontologia e Stratigrafia, 2017
Shell-beds rich in shell fragments are very common in the Lombardia basinal facies in the Late Triassic. Biofragmentation by durophagous fishes, which were very common, must be regarded as the main taphonomic process on the basis of the shape of ...

Hindlimb functional morphology and locomotor biomechanics of the small Late Triassic pseudosuchian reptile Gracilisuchus stipanicicorum (Archosauria: Gracilisuchidae)

Journal of Anatomy, EarlyView.
A three‐dimensional biomechanical model of the musculoskeletal system is used to analyse the potential locomotor functions of the small (~1 kg) Late Triassic archosaurian reptile Gracilisuchus stipanicicorum. The study finds that, potentially like the ancestral archosaur, this taxon was probably quadrupedal, plantigrade and neither strongly sprawling ...

Depositional Facies, Sequence Stratigraphy, and Diagenesis of Lower Cretaceous Carbonate Reservoir, Southern Iraq: Implications for Petroleum Exploration

Journal of Petroleum Geology, EarlyView.
ABSTRACT The Lower Cretaceous Yamama Formation of southern Iraq represents a key carbonate reservoir within Iraq and the Middle East, yet its complex depositional facies architecture and diagenetic alterations present challenges for predicting reservoir quality.

The Stratigraphic Record of Pre-breakup Geodynamics: Evidence from the Barrow Delta, offshore Northwest Australia [PDF]

, 2016
The structural and stratigraphic evolution of rift basins and passive margins has been widely studied, with many analyses demonstrating that delta systems can provide important records of post-rift geodynamic processes.

Provenance analysis of the Late Triassic Yichuan Basin: constraints from zircon U-Pb geochronology

Open Geosciences, 2018
Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) U-Pb dating has been performed on detrital zircons from the Chunshuyao Formation sandstone of Yichuan Basin.
