Marine snowstorm during the Permian-Triassic mass extinction (2023)
Journal Article
Grasby, S. E., Ardakani, O. H., Liu, X., Bond, D. P. G., Wignall, P. B., & Strachan, L. J. (2024). Marine snowstorm during the Permian-Triassic mass extinction. Geology, 52(2), 120-124. https://doi.org/10.1130/G51497.1

The Permian-Triassic mass extinction (PTME) interval is marked by major excursions in both inorganic and organic carbon (C) isotopes. Carbon cycle models predict that these trends were driven by large increases in productivity, yet organic C-rich roc... Read More about Marine snowstorm during the Permian-Triassic mass extinction.

The great catastrophe: causes of the Permo-Triassic marine mass extinction (2023)
Journal Article
Wignall, P. B., & Bond, D. P. G. (2024). The great catastrophe: causes of the Permo-Triassic marine mass extinction. National Science Review, 11(1), Article nwad273. https://doi.org/10.1093/nsr/nwad273

The marine losses during the Permo-Triassic mass extinction were the worst ever experienced. All groups were badly affected, especially amongst the benthos (e.g. brachiopods, corals, bryozoans, foraminifers, ostracods). Planktonic populations underwe...

Global oceanic anoxia linked with the Capitanian (Middle Permian) marine mass extinction (2023)
Journal Article
Song, H., Algeo, T., Song, H., Tong, J., Wignall, P., Bond, D. P., …Anbar, A. (2023). Global oceanic anoxia linked with the Capitanian (Middle Permian) marine mass extinction. Earth and planetary science letters, 610, Article 118128. https://doi.org/10.1016/j.epsl.2023.118128

The timing and causation of the Capitanian (late Middle Permian) biocrisis remain controversial. Here, a detailed uranium-isotopic (δ238U) profile was generated for the mid-Capitanian to lower Wuchiapingian of the Penglaitan section (the Guadalupian/...

Middle Jurassic terrestrial environmental and floral changes linked to volcanism: Evidence from the Qinghai-Tibet Plateau, China (2023)
Journal Article
Zhang, P., Yang, M., Lu, J., Jiang, Z., Zhou, K., Liu, H., …Bond, D. P. (2023). Middle Jurassic terrestrial environmental and floral changes linked to volcanism: Evidence from the Qinghai-Tibet Plateau, China. Global and planetary change, 223, Article 104094. https://doi.org/10.1016/j.gloplacha.2023.104094

The breakup of Pangaea and the rapid opening of the Ligurian and Central Atlantic oceans during the Middle Jurassic resulted in widespread volcanism accompanied by significant shifts in global environments, climates, and floras. Although major volcan... Read More about Middle Jurassic terrestrial environmental and floral changes linked to volcanism: Evidence from the Qinghai-Tibet Plateau, China.

An astronomical timescale for the Permian-Triassic mass extinction reveals a two-step, million-year-long terrestrial crisis in South China (2023)
Journal Article
Hua, F., Shao, L., Zhang, T., Bond, D. P., Wang, X., Wang, J., …Hilton, J. (2023). An astronomical timescale for the Permian-Triassic mass extinction reveals a two-step, million-year-long terrestrial crisis in South China. Earth and planetary science letters, 605, Article 118035. https://doi.org/10.1016/j.epsl.2023.118035

The Permian-Triassic Mass Extinction (PTME) is the greatest biotic crisis of the Phanerozoic. In terrestrial settings, the PTME appears to have been diachronous and it has been suggested that losses initiated before the marine crisis. We examine orga...
