Rise of present-day tetrapods in the paleotropics of Late Triassic equatorial Pangaea: new insights from microvertebrate data
… paleocommunity record of Triassic equatorial Pangaea. My first chapter describes and analyzes an assemblage of gymnophionomorph (stem caecilian) bones from PFV 456 which represent the oldest-known caecilian fossils globally. As the oldest caecilian fossils, they provide new support for the …

From Gondwanaland, with love : the tale of how Boston got its rocks
… as we know it, the formation and destruction of Pangaea, and the rise and fall of the dinosaurs. More than that, though: the history of our understanding of Boston's journey illustrates how geologists think about their world, and how their ideas have changed over the last 150 years in one of …

Biogeochemical proxies for environmental and biotic conditions at the Permian-Triassic boundary
… situated in the northwest of the supercontinent Pangaea. The Great Bank of Guizhou, China is the third section studied, and it is a carbonate platform deposited on the southern edge of one of the smaller continental blocks that formed the eastern margin of the Paleo-Tethys Ocean. The fourth …

Late Paleozoic basin analysis of the Loppa High and Finnmark Platform in the Norwegian Barents Sea : integration of seismic attributes and seismic sequence stratigraphy
… Sea was located along the northern margin of Pangaea, which experienced a northward drift at a speed of ~2–3 mm per year. This gradual shift in the paleolatitudinal position is reflected by changes in regional climatic conditions: from warm-humid in the early Carboniferous, changing to …

Extinction and recovery dynamics of Triassic-Jurassic macro-invertebrate communities
… the ecosystem in different localities throughout Pangaea. To address this, four localities were studied: St. Audrie’s Bay, Larne and Pinhay Bay in the UK, and Portezuelo Providencia in Chile. From each locality, samples were taken at approximately 1m intervals throughout the Tr/J sections. Species …

A Practice-Led Inquiry into Collaboration with Landscape within the Expanded Field of Photography
… non-human agency at a tin and arsenic mine; the Pangaea plate considers the agents at play alongside the aesthetics framed through the concept of indeterminacy; the Paragenesis plate explores the entangled nature of deploying diffractive methods through the concept of intra-action; the Tectonics …

The Karoo sand sea in changing climates: Early Jurassic interdune lakes and erg dynamics in southern Africa
… vast ancient desert system that was active over Pangaea and formed part of one of the largest known sand seas in Earth's history. The Lower Jurassic Clarens Formation in the main Karoo Basin of southern Africa has been interpreted as an aeolian succession that is dominated by massive sandstones …
