Triassic beds in the basement of the Adriatic-Dinaric carbonate platform of Mt. Svilaja (Croatia)

open access: yesGeologija, 2003
On the southwestern slope of Mt. Svilaja a Triassic sequence is exposed. It is composed of Lower Triassic carbonate siliciclastic shelf beds that are unconformably overlain by Anisian breccia.

Lithofacies palaeogeography as a guide to petroleum exploration

open access: yesJournal of Palaeogeography, 2013
Lithofacies palaeogeography as a guide to petroleum exploration is a very important topic. By using the following five exploration examples, this paper discusses the guide of lithofacies palaeogeography or of sedimentary facies to petroleum exploration ...

The effects of the spreading of the Central Atlantic during the Middle Jurassic on dinosaur faunas [PDF]

open access: yes, 2012
The spreading of the Central Atlantic is a complex series of events that include a ridge jump to the east and a ridge jump to the west at c. 170Ma and c. 162Ma respectively.

Voltziopsis, a southern conifer of lower Triassic age

open access: yesPapers and proceedings of the Royal Society of Tasmania, 1967
Shoots ascribed to Voltziopsis africana Seward are described, with cuticular detail. These compare very closely with the shoot system, with an attached seed cone, caned V. wolganensis sp. nov., which is associated with pollen of the Strotersporites Wilson sort.

Aftermath of the Permian-Triassic mass extinction event: Paleoecology of Lower Triassic carbonates in the western USA

open access: yesPalaeogeography, Palaeoclimatology, Palaeoecology, 1995
Paleoecologic study of invertebrate faunas from three successive Early Triassic seaways reveals that biotic recovery from the end-Permian mass extinction event was slow, and that full recovery did not occur until after the Early Triassic. Simple, cosmopolitan, opportunistic generalists, and low-diversity, low-complexity paleocommunities were ...

Comparative histological analysis of vertebrates reveals Triassic climate variability across southern Pangea

open access: yesJournal of Anatomy, EarlyView.
Bone tissues of Triassic taxa reveal life history signals consistent with climatic variation across southern Pangea, spanning present‐day Brazil, Argentina, Zimbabwe, and India. Slower growth patterns within the Zimbabwean assemblage suggest a comparatively more arid intracontinental environment than those closer to the coast. Artwork by Andrey Atuchin.

A giant Late Triassic ichthyosaur from the UK and a reinterpretation of the Aust Cliff 'dinosaurian' bones.

open access: yesPLoS ONE, 2018
The largest reported ichthyosaurs lived during the Late Triassic (~235-200 million years ago), and isolated, fragmentary bones could be easily mistaken for those of dinosaurs because of their size.

LOWER TRIASSIC (INDUAN TO OLENEKIAN) CONODONTS, FORAMINIFERA AND BIVALVES FROM THE AL MAMALIH AREA, DEAD SEA, JORDAN: CONSTRAINTS ON THE P-T BOUNDARY

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2018
Upper Permian to Lower Triassic successions exposed in the Al Mamalih area, east of the Dead Sea, Jordan record the transition between the alluvial Umm Irna Formation (Upper Permian) and the overlying shallow marine Ma’in Formation (Lower Triassic).

Conodont Paleoecology of Lower Triassic Thaynes Formation: ABSTRACT [PDF]

open access: yesAAPG Bulletin, 1983
The Lower Triassic (Smithian) Thaynes Formation represents a broad spectrum of paleoenvironments. Samples arranged along a generalized depth-salinity environmental gradient from tidal flats to a relatively deep, commonly dysaerobic, basin yielded a conodont fauna of 30 form elements.

Structural geology and favorable exploration prospect belts in northwestern Sichuan Basin, SW China

open access: yesPetroleum Exploration and Development, 2019
The northwestern Sichuan region has experienced multi-stage tectonic evolution including marine cratonic basin from the Sinian to the Middle Triassic and intra-continental basin from the Late Triassic to the Cenozoic. Several regional tectonic activities
