Functional morphology and biomechanics of the locomotor apparatus in the large Late Triassic carnivore Postosuchus kirkpatricki (Archosauria: Rauisuchidae)

Journal of Anatomy, EarlyView.
A three‐dimensional model is used to analyze the locomotor biomechanics of the large Late Triassic archosaurian reptile Postosuchus kirkpatricki. The study finds that it is more uncertain than previously concluded whether it was quadrupedal or bipedal, and plantigrade or digitigrade, but it clearly had locomotor specializations including large hindlimb

Reconstructing the major skull myology of the giant stem‐amphibian Mastodonsaurus: A case study for early tetrapods

Journal of Anatomy, EarlyView.
We reconstruct the major cranial musculature of the giant stem amphibian Mastodonsaurus giganteus, revealing a differentiated jaw‐adductor system, a probable sesamoid pulley, and previously unrecognised muscles. This EPB‐based case study establishes an anatomical framework for modelling feeding in early tetrapods and supports interpretations of ...

Feldspar Albitization With Implications for Reservoir Quality Evolution of Eocene Turbidite Sandstones in Offshore Espírito Santo Basin, Eastern Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT The diagenetic albitization of plagioclase and K‐feldspar grains is a transformative process that significantly alters sandstone's detrital composition and formation water chemistry, impacting reservoir quality. In this study, Eocene turbidite sandstones from the offshore Espírito Santo Basin, Brazil, were investigated to elucidate the role of

Late Triassic marine reptiles.

, 2018
During faunal recovery after the Permo-Triassic mass extinction (PTME), several tetrapod lineages independently evolved adaptations to marine life. Thus reptiles became significant elements of marine environments already at the beginning of the Mesozoic ...

Characteristics of Chang 7 shale gas reservoirs in Triassic Yanchang Formation of Ordos Basin and its exploration and development prospects

Shiyou shiyan dizhi
As the second-largest sedimentary basin in China, the Ordos Basin has enormous potential for oil and gas exploration. The Chang 7 member of the Triassic Yanchang Formation in the basin is extensively distributed with organic-rich source rocks, covering ...

Early development of anoxia prior to the main euxinic phase of the Jenkyns Event on the margin of the Western Tethys (Sachrang Basin, Eastern Alps)

Sedimentology, EarlyView.
ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethyan basins, where hydrography potentially played a minor role, is poorly ...
