The Carnian Pluvial Episode (Late Triassic) was a time of global environmental changes
and possibly substantial coeval volcanism. The extent of the biological turnover in marine …

The P ermian and T riassic were key time intervals in the history of life on E arth. Both
periods are marked by a series of biotic crises including the most catastrophic of such …

Examining the geological past of our planet allows us to study periods of severe climatic and
biological crises and recoveries, biotic and abiotic ecosystem fluctuations, and faunal and …

Ray‐finned fishes (A ctinopterygii) constitute approximately half of all living vertebrate
species. A stable hypothesis of relationships among major modern lineages has emerged …

Tunas, lamnid sharks, modern whales, and derived ichthyosaurs converged on the
thunniform body plan, with a fusiform body, lunate caudal fin, compressed peduncle, and …

Bony fishes are the principal group of backboned animals in contemporary aquatic settings.
Extant species are the focus of a vigorous program of macroevolutionary research, but …

The phylogenetic relationships of the recently described genus† Ticinolepis from the Middle
Triassic of the Monte San Giorgio are explored through cladistic analyses of the so far …

Marine biochemical cycles underwent profound changes across the Permian–Triassic (P–T)
boundary, coinciding with Phanerozoic's most devastating mass extinction. This review …

The mass extinction characterizing the Permian/Triassic boundary (PTB;~ 252 Ma)
corresponds to a major faunal shift between the Palaeozoic and the Modern evolutionary …

The origin of the largest modern vertebrate group, the Teleostei, saw major refinements in
the last decades, thanks to newly discovered and stratigraphically closely spaced Triassic …
