Triassic Revolution [PDF]

open access: yesFrontiers in Earth Science, 2022
The Triassic has long been recognized as a time during which marine and terrestrial ecosystems modernized dramatically, and it seems to have been a two-step process.

Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The craniomandibular anatomy of the early archosauriform Euparkeria capensis and the dawn of the archosaur skull [PDF]

open access: yesRoyal Society Open Science, 2020
Archosauria (birds, crocodilians and their extinct relatives) form a major part of terrestrial ecosystems today, with over 10 000 living species, and came to dominate the land for most of the Mesozoic (over 150 Myr) after radiating following the Permian ...

40 years of field work in the Triassic marine vertebrate sites [PDF]

open access: yesResearch & Knowledge, 2017
During the first 70 years of the XX century very few researches have concerned the marine Triassic fishes. They were prevalently related to the many scientific expeditions carried out in the first half of that century in localities situated along the ...

New skulls of the basal sauropodomorph Plateosaurus trossingensis from Frick, Switzerland: Is there more than one species? [PDF]

open access: yesActa Palaeontologica Polonica, 2021
The Triassic basal sauropodomorph Plateosaurus trossingensis is well-known from mass accumulations at the German localities of Trossingen and Halberstadt and the Swiss locality of Frick, and is significant especially regarding its taphonomy and proposed ...

Pre-Carpels from the Middle Triassic of Spain

open access: yesPlants, 2022
In stark contrast to the multitude of hypotheses on carpel evolution, there is little fossil evidence testing these hypotheses. The recent discovery of angiosperms from the Early Jurassic makes the search for precursors of angiosperm carpels in the ...

A Triassic crown squamate

open access: yesScience Advances, 2022
Mammals, birds, and squamates (lizards, snakes, and relatives) are key living vertebrates, and thus understanding their evolution underpins important questions in biodiversity science. Whereas the origins of mammals and birds are relatively well understood, the roots of squamates have been obscure.

Postcranial osteology of the first early-stage juvenile skeleton of Plateosaurus trossingensis from the Norian of Frick, Switzerland [PDF]

open access: yesActa Palaeontologica Polonica, 2020
Owing to monospecific mass-accumulation sites in Central Europe, the early-branching sauropodomorph Plateosaurus has one of the best fossil records among dinosaurs. Despite this, early-stage juveniles have been conspicuously absent.

From shallow-water carbonate ramp to hemipelagic deep-marine carbonate deposition: Part 2. Sirogojno (Klisura quarry) - the reference section of the Middle to Late Anisian Bulog sedimentary succession in the Inner Dinarides (SW Serbia) [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2023
The Middle to Late Anisian sedimentary succession preserved in the Klisura quarry in Sirogojno (Zlatibor Mt., SW Serbia) preserves the most complete deepening depositional history in the Inner Dinarides in Serbia.
