Large igneous provinces and mass extinctions
- P. Wignall
- Geology
- 1 March 2001
Comparing the timing of mass extinctions with the formation age of large igneous provinces reveals a close correspondence in five cases, but previous claims that all such provinces coincide with… Expand
Mass Extinctions and Their Aftermath
- C. Marshall, A. Hallam, P. Wignall
- Biology
- 1997
This is a systematic review of the major mass extinctions in the history of life. It covers all groups of organisms - plant, animal, terrestrial, and marine - that have become extinct alongside the… Expand
Lethally Hot Temperatures During the Early Triassic Greenhouse
- Yadong Sun, M. Joachimski, +5 authors X. Lai
- Environmental Science, Medicine
- Science
- 19 October 2012
Too-Hot Times Climate warming has been invoked as a factor contributing to widespread extinction events, acting as a trigger or amplifier for more proximal causes, such as marine anoxia. Sun et al.… Expand
Oceanic Anoxia and the End Permian Mass Extinction
- P. Wignall, R. J. Twitchett
- Geology, Medicine
- Science
- 24 May 1996
Data on rocks from Spitsbergen and the equatorial sections of Italy and Slovenia indicate that the world's oceans became anoxic at both low and high paleolatitudes in the Late Permian. Such… Expand
Rapid and synchronous collapse of marine and terrestrial ecosystems during the end-Permian biotic crisis
- R. J. Twitchett, C. Looy, R. Morante, H. Visscher, P. Wignall
- Geology
- 1 April 2001
A newly studied Permian-Triassic (P-Tr) boundary section in Jameson Land, East Greenland, contains an abundant and well-preserved marine fauna as well as terrestrial palynomorphs. For the first time… Expand
Large shifts in the isotopic composition of seawater sulphate across the Permo–Triassic boundary in northern Italy
- R. Newton, E. L. Pevitt, P. Wignall, S. Bottrell
- Geology
- 15 February 2004
Carbonate-associated sulphate (CAS) extracted from a Permo–Triassic succession at Siusi in northern Italy is shown to preserve a true seawater-sulphate isotope record. Two periods of increasing δ34S… Expand
Triassic climates — State of the art and perspectives
- Nereo Preto, Nereo Preto, Evelyn Kustatscher, P. Wignall
- Geology
- 15 April 2010
Abstract The climate of the Triassic period was characterized by a non-zonal pattern, dictated by a strong global monsoon system with effects that are most evident in the Tethys realm. This strong… Expand
