Evolution and relationships of the conifer seed cone telemachus: Evidence from the triassic of antarctica [PDF]
, 2010 The seed cone Telemachus is known from several Triassic localities in Gondwana. New specimens from two localities in Antarctica provide additional information about the type species, Telemachus elongatus, based on details of morphology and anatomy ...

The Triassic radiation of the entomofauna
Comptes Rendus Palevol, 2005 Assessing the insect evolution around the Permian/Triassic boundary faces various pitfalls. The taxonomic and phylogenetic frames are not consensually established, and diverse evidences suggest that the record is incomplete. Nevertheless, extensive studies in progress on the super-ordinal clades Archaeorthoptera and Odonatoptera reveal common trends ...

Thermal conductivity of Triassic evaporites
Geophysical Journal International, 2021 SUMMARY Evaporites occur in various geological environments: sedimentary basins, orogenic belts, where they often act as tectonic decoupling layers, and as top-seals in hydrocarbon fields. In all cases, they affect the temperature distribution in the upper crust, as their thermal conductivity is relatively higher with respect to other ...

, 2015 The Central Asian Orogenic Belt records the accretion and convergence of three collage systems that were finally rotated into two major oroclines. The Mongolia collage system was a long, N–S-oriented composite ribbon that was rotated to its current ...

On the Triassic of Massachusetts [PDF]
Geological Society of America Bulletin, 1891 Introduction Difficulties in the Way of Correlation .—The sudden and irregular transitions from the coarsest to the finest sediments, the derivation of many of the coarse beds from rocks not known in place among the crystallines of the surrounding region, and the prevailing easterly dips have made the correlation and explanation of the Triassic ...

An enigmatic new archosauriform from the Carnian– Norian, Upper Triassic, Ischigualasto Formation of northwestern Argentina [PDF]
Acta Palaeontologica Polonica, 2021 In this contribution we introduce a new Late Triassic archosaur, Incertovenator longicollum gen. et sp. nov., with an unusual combination of character states that are present in certain early avemetatarsalian and pseudosuchian archosaur clades.

Decoupling of morphological disparity and taxic diversity during the adaptive radiation of anomodont therapsids [PDF]
, 2013 Adaptive radiations are central to macroevolutionary theory. Whether triggered by acquisition of new traits or ecological opportunities arising from mass extinctions, it is debated whether adaptive radiations are marked by initial expansion of taxic ...

Taxonomic revision of Asialepidotus shingyiensis Su, 1959 (Halecomorphi, Holostei) from the Middle Triassic (Ladinian) of Guizhou and Yunnan, China [PDF]
Research & Knowledge, 2017 The holostean fish Asialepidotus shingyiensis, from the Middle Triassic (Ladinian) of Guizhou and Yunnan, China, was previously regarded as either a semionotiform ginglymodian or an amiiform halecomorph.

Triassic Eustatic Variations Reexamined
GSA Today, 2018 Documentation of eustatic variations for the Triassic is limited by the paucity of the preserved marine stratigraphic record, which is confined mostly to the low and middle paleolatitudes of the Tethys Ocean.
