Evidence for Late Triassic crustal suturing of the Central and Southern Pamir

Journal of Asian Earth Sciences: X, 2020
The timing of closure of the Paleotethys and Rushan ocean basins and suturing of Gondwanan crustal fragments in the Pamir is not well resolved. Whereas the Central Pamir terrane is generally interpreted to have collided with the Northern Pamir terrane at

Bioerosion traces in bones reveal an increase in ethological diversity in the insect exploitation of carcasses in the late Triassic

The Anatomical Record, EarlyView.
Abstract This study presents the first detailed description of bioerosion traces produced by insects in bones from the Santa Cruz Sequence (early Carnian, Santa Maria Supersequence, Brazil). An array of traces is reported, consisting of notches, a tube, trails of grooves attributed to the ichnotaxon Osteocallis mandibulus and ornamented depressions ...

REDESCRIPTION OF ‘PERLEIDUS’ (OSTEICHTHYES, ACTINOPTERYGII) FROM THE EARLY TRIASSIC OF NORTHWESTERN MADAGASCAR

Rivista Italiana di Paleontologia e Stratigrafia, 2017
The revision of the material from the Lower Triassic fossil-bearing-nodule levels from northwestern Madagascar supports the assumption that the genus Perleidus De Alessandri, 1910 is not present in the Early Triassic.

Cortical bone geometry and static gravitational loads in neosauropod dinosaurs: Implications for biomechanical constraints on terrestrial gigantism

The Anatomical Record, EarlyView.
Abstract Sauropod dinosaurs achieved unprecedented terrestrial gigantism, raising questions about the biomechanical limits of bone under extreme gravitational loads. We estimated static gravitational pressures (Pg) on appendicular cortical bone in neosauropods, including diplodocoids, brachiosaurids, and titanosaurs.

Regime Shifts in an Early Triassic Subtropical Ecosystem

Frontiers in Earth Science, 2020
The Early Triassic was one of the most remarkable time intervals in Earth History. To begin with, life on Earth had to face one of the largest subaerial volcanic degassing, the Siberian Traps, followed by a plethora of accompanying environmental hazards ...

Geological carbon dioxide storage in the German North Sea: Static‐to‐dynamic capacity refinement for a 10 Mt/y injection scenario

Deep Underground Science and Engineering, EarlyView.
This study assesses whether a saline aquifer in the German North Sea can sustain industrial‐scale CO2 injection at 10 Mt/year over 30 years. A 3D reservoir model is used to compare static capacity with dynamically achievable storage. The work links site‐scale injection strategy design with basin‐scale pressure response, providing a framework for ...

Renewable energy mapping in Northeastern Morocco: A geographic information system‐based comparison of geothermal, solar, and wind potential in the Guercif‐Guilliz and Beni Snassen regions

Deep Underground Science and Engineering, EarlyView.
The graphical abstract summarizes a geographic information system (GIS)‐based synthesis of renewable energy resources in Northeastern Morocco, focusing on the Guercif‐Guilliz and Beni Snassen areas. It visually presents the spatial distribution of solar irradiation and wind energy potential derived from available datasets, alongside their relationship ...

Orthodentine‐osteodentine and osteocytic‐anosteocytic transition inferred from Silurian stem chondrichthyan dermal jawbones with ever‐white teeth overgrown by brown denticles

Developmental Dynamics, EarlyView.
Abstract Background The dentigerous jawbones of a 423‐million‐year‐old stem chondrichthyan (ischnacanthid acanthodian) carry a characteristic combination of multi‐row non‐shedding white teeth with brownish overgrowing denticles. The color distinction makes it a good model for observing the interaction between two odontode lineages, but the nature of ...

A new Triassic austrolimulid from Poland presents insight into xiphosurid evolution and palaeobiogeography at the dawn of the Mesozoic [PDF]

PeerJ
Xiphosurids are aquatic chelicerates widely viewed as examples of so-called ‘living fossils’ due to their apparent morphological conservatism and limited diversity since at least the Jurassic.

Quantitative Insights into Atomic Scale Oil–Clay Adhesion Governing Shale Oil Retention and Mobility

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Atomic force microscopy reveals a clear adhesion hierarchy between shale oil and clay minerals, governed by nanoscale surface chemistry. Strong interactions on chlorite and illite arise from abundant polar sites and cation bridging, whereas weaker coupling on montmorillonite limits interfacial binding.
