Bio- and chronostratigraphy of the Middle Triassic Reifling Formation of the westernmost Northern Calcareous Alps [PDF]

open access: yes, 2018
New finds of fossils including bivalves, ammonoids, brachiopods and palynomorphs from the Middle Triassic Reifling Formation significantly improve the age assignment for this unit in Liechtenstein and Vorarlberg.

A large aberrant stem ichthyosauriform indicating early rise and demise of ichthyosauromorphs in the wake of the end-Permian extinction [PDF]

open access: yes, 2016
Contrary to the fast radiation of most metazoans after the end-Permian mass extinction, it is believed that early marine reptiles evolved slowly during the same time interval.

Detailed conodont data from the Olenekian–Anisian boundary interval of the GSSP candidate section at Deşli Caira, Romania [PDF]

open access: yesJournal of Micropalaeontology
The Olenekian–Anisian boundary (OAB) interval is an important time in Earth's history, reflecting the last phase of marine ecosystem recovery in the aftermath of the end-Permian mass extinction.

STRATIGRAFIA E PALEOGEOGRAFIA ANISICHE DELLE ALPI GIULIE OCCIDENTALI (ALPI MERIDIONALI - ITALIA)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2020
Stratigraphic and sedimentologic studies of the Anisian sediments outcropping in North West Friuli allowed the reinterpretation of the stratigraphic sequence and the reconstruction of the paleogeographic and structural evolution of this area.

THE EARLY-MIDDLE TRIASSIC BOUNDARY AT CHIOS (GREECE)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2017
The sections of Marathovouno hillock in Chios (Greece), proposed by Assereto (1974) as stratotype for the base of the Anisian, have been revisited. An additional new section, Parthenis, near the town of Chios, was also considered.

Triassic: seasonal rivers, dusty deserts and saline lakes [PDF]

open access: yes, 2006
The collision of Siberia and the Kazakstan microplate with the eastern side of the Fennoscandia continent in the Permian amalgamated the last major continental fragments to produce the supercontinent Pangaea, which persisted into the Jurassic (1). During

Triassic (Anisian and Rhaetian) palaeomagnetic poles from the Germanic Basin (Winterswijk, the Netherlands)

open access: yesJournal of Palaeogeography, 2019
In this paper, we provide two new Triassic palaeomagnetic poles from Winterswijk, the Netherlands, in the stable interior of the Eurasian plate. They were respectively collected from the Anisian (~ 247–242 Ma) red marly limestones of the sedimentary ...

Integrated Sr isotope variations and global environmental changes through the Late Permian to early Late Triassic [PDF]

open access: yes, 2015
New 87Sr/86Sr data based on 127 well-preserved and well-dated conodont samples from South China were measured using a new technique (LA-MC-ICPMS) based on single conodont albid crown analysis. These reveal a spectacular climb in seawater 87Sr/86Sr ratios

Rare Middle Triassic coleoids from the Alpine-Carpathian system: new records from Slovakia and their significance

open access: yesSwiss Journal of Palaeontology
Two stratigraphically well constrained (by ammonites and conodonts) coleoid remains have been recorded from the Triassic (Anisian) dark-grey organodetritic limestones (Ráztoka Limestone) of Western Carpathians (Hronic Nappe).

New Stratigraphic and Palaeogeographic Results from the Palaeozoic and Early Mesozoic of the Middle Pontides (Northern Turkey) in the Azdavay, Devrekani, Küre and Inebolu Areas: Implications for the Carboniferous-Early Cretaceous Geodynamic Evolution and Some Related Remarks to the Karakaya Oceanic Rift Basin [PDF]

open access: yes, 2000
The Küre Complex of the Middle Pontides, northern Turkey, is not a remnant of the Palaeotethys but consists of three different units with differing geological history, the Küre Ridge Unit, the Küre Ocean Unit and the Çalça Unit.
