The Permian and Triassic represent a time of major global climate change from icehouse to hothouse conditions and significant (∼25°) northward motion of landmasses amalgamated in essentially one supercontinent, Pangea. The greatest of all mass extinctions occurred around the Permian-Triassic boundary (251 Ma), although there is no consensus regarding the cause(s). Recent studies have suggested a meteor impact and worldwide die-off of vegetation, on the basis of sparse local observations…

A palaeobotanical perspective on the great end-Permian biotic crisis

Abstract Mass extinctions are crucial to understanding changes in biodiversity through time. However, it is still disputed whether extinction dynamics in the marine and terrestrial biotas followed

No mass extinction for land plants at the Permian–Triassic transition

It is shown that the apparent plant mass extinction is a result of biases in the fossil record and their reanalysis suggests a lower magnitude and more selective plant extinction.

Palaeophytogeographical Patterns Across the Permian–Triassic Boundary

It has long been recognized that terrestrial floras underwent major and long-lasting changes during the Permian and Triassic, some of which have been attributed to the end-Permian mass extinction.

The greatest loss of biodiversity in the history of animal life occurred at the end of the Permian Period (∼252 million years ago). This biotic catastrophe coincided with an interval of widespread

[1] The causes for the Permian-Triassic Boundary (PTB) extinction, the largest mass extinction on record, remain enigmatic. The period is marked by large-scale volcanic eruptions and evidence for

Altered river morphology in south africa related to the permian-triassic extinction

Evidence from correlative nonmarine strata elsewhere in the world containing fluvial Permian-Triassic boundary sections suggests that a catastrophic terrestrial die-off of vegetation was a global event, producing a marked increase in sediment yield as well as contributing to the global delta(13)C excursion across the Permians-Tri Jurassic boundary.

Permian-Triassic Life Crisis on Land

The Permian-Triassic boundary at 251 million years ago was a time of abrupt decline in both diversity and provincialism of floras in southeastern Australia and extinction of the Glossopteris flora.

Palaeosols across the Permian‐Triassic boundary in Antarctica provide evidence of a marked change in ecosystems at this greatest of all extinctions in the history of life on Earth. The boundary can

Abstract The climatic influences on vegetation in the present world can serve as an excellent model for the Permian, there being approximately the same level of floral differentiation and the same

Global coal gap between Permian-Triassic extinction and Middle Triassic recovery of peat-forming plants

Early Triassic coals are unknown, and Middle Triassic coals are rare and thin. The Early Triassic coal gap began with extinction of peat-forming plants at the end of the Permian (ca. 250 Ma), with no

Simulations of Permian Climate and Comparisons with Climate‐Sensitive Sediments

We use a climate model to simulate two intervals of Permian climate: the Sakmarian (ca. 280 Ma), at the end of the major Permo‐Carboniferous glaciation, and the Wordian (ca. 265 Ma). We explore the
