Reassessment of the evidence for postcranial skeletal pneumaticity in Triassic archosaurs, and the early evolution of the avian respiratory system. [PDF]

, 2012
Uniquely among extant vertebrates, birds possess complex respiratory systems characterised by the combination of small, rigid lungs, extensive pulmonary air sacs that possess diverticula that invade (pneumatise) the postcranial skeleton, unidirectional ...

Microsculpture study of Late Permian and Early Triassic conchostracans from the Babii Kamen section (Western Siberia)

Учёные записки Казанского университета: Серия Естественные науки, 2019
The microsculpture of Permian and Triassic conchostracans from the Babii Kamen section (Western Siberia) was studied in order to determine the significance of microsculpture inthe taxonomy of conchostracan species.

EARLY TRIASSIC ORIGIN OF COCCOLITHOGENESIS

RIVISTA ITALIANA DI PALEONTOLOGIA E STRATIGRAFIA
Calcareous nannofossil investigations were conducted on Lower and Middle Triassic marine successions from South China. Coccoliths, nannoliths and calcispheres are relatively frequent and moderately preserved, showing an increase in diversity from the Smithian (Olenekian) to the Ladinian.

A new archosauromorph from South America provides insights on the early diversification of tanystropheids.

PLoS ONE, 2020
After the Permo-Triassic mass extinction, the archosauromorph fossil record is comparatively abundant and ecologically diverse. Among early archosauromorphs, tanystropheids gained considerable attention due to the presence of extreme skeletal adaptations

Early Triassic recovery of echinoderms

Comptes Rendus Palevol, 2005
Abstract The Permian–Triassic mass extinction interval was an important time in the evolutionary history of the echinoderms. Details of the extinction and, in particular the immediate post-extinction recovery in the Early Triassic, are seldom addressed because of a perception that the Permian–Triassic echinoderm fossil record is too poor.

Continental weathering in the Early Triassic in Himalayan Tethys, central Nepal: Implications for abrupt environmental change on the northern margin of Gondwanaland [PDF]

, 2014
The geochemistry of Triassic mudstones in the Himalayan Tethys sequence, central Nepal, was studied with respect to changes in sedimentary facies, grain size, and source rocks. The Triassic sedimentary facies of mudstone and carbonates show deposition in

There was no “Great Bank of Guizhou” in the Early Triassic in Guizhou Province South China

Journal of Palaeogeography, 2015
In the 1990s, some geologists named the Early Triassic isolated carbonate platform in the Luodian area of southern Guizhou Province in South China as the “Great Bank of Guizhou”. During the past twenty years, this term “Great Bank of Guizhou” was used in

Morphological and biomechanical disparity of crocodile-line archosaurs following the end-Triassic extinction [PDF]

, 2013
Mesozoic crurotarsans exhibited diverse morphologies and feeding modes, representing considerable ecological diversity, yet macroevolutionary patterns remain unexplored.

The Triassic climate and its evolutionary characteristics in Jiyuan area in south of North China Plate： Evidence from paleosol geochemistry

河南理工大学学报. 自然科学版
ObjectivesThe Triassic period was a period of rapid fluctuation of greenhouse climate， and the paleosol recorded abundant paleoclimate information. To study the climate change process from extreme to medium greenhouse，Methodsthe Triassic paleosoils in ...
