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.

Synopsis of the Triassic reptiles from Germany [PDF]

open access: yesFossil Record
Triassic strata in the portion of the Central European Basin (CEB) that cover parts of conterminous Germany have yielded a long if discontinuous record of continental tetrapods spanning this period.

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 ...

Apatite in Carbonatite Preserving Primary Magmatic, Post‐Magmatic Overgrowth, and Post India‐Asia Collision‐Related Hydrothermal Alteration: Evidenced From U–Pb Isotope and Trace Element Geochemistry

open access: yesGeological Journal, EarlyView.
U–Pb isotope and trace element geochemistry of apatite from carbonatites of Peshawar Plain Alkaline Igneous Province, western Himalaya shows Permo‐Carboniferous magmatism, an additional magmatic pulse during Cretaceous, and post‐magmatic hydrothermal/metasomatism during Oligocene. ABSTRACT U–Pb isotope and trace element geochemistry of apatite combined

NEW BIOSTRATIGRAPHIC DATA ON THE TRIASSIC OF THE MARATHOVOUNO HILLOCK AREA (CHIOS ISLAND, GREECE)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2017
The Island of Chios (northern Egean Sea, Greece) is known for a well-preserved Paleozoic to Mesozoic sedimentary sequence. This paper is  focused on the micropaleontology and biostratigraphy of the Marmarotrapeza Formation (Lower/Middle Triassic) and of ...

Lateral Carbon Transport Induced by Watershed Erosion: Driving Effects of Land Use, Rainfall, and Landscape Controls

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Lateral carbon transport induced by soil erosion is a key component of the global carbon cycle. Over the past 50 years, ecological restoration projects in the Loess Plateau of China have increased vegetation coverage. However, the effects of land use, precipitation variability, and landscape factors on lateral carbon transport remain unclear ...

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).

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.

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.

Mortars From Punic and Hellenistic–Roman Solunto: Materials, Formulations, and Technology

open access: yesArchaeometry, EarlyView.
ABSTRACT This study presents an archaeometric investigation of 18 hydraulic rendering and bedding mortars from Punic and Hellenistic–Roman Solunto (NW Sicily). The research aimed to characterize raw materials, reconstruct manufacturing sequences, and evaluate technological proficiency through mineralogical and petrochemical analyses.
