Tellurium in Late Permian-Early Triassic Sediments as a Proxy for Siberian Flood Basalt Volcanism (2020)
Journal Article
Regelous, M., Regelous, A., Grasby, S. E., Bond, D. P., Haase, K. M., Gleißner, S., & Wignall, P. B. (2020). Tellurium in Late Permian-Early Triassic Sediments as a Proxy for Siberian Flood Basalt Volcanism. Geochemistry, geophysics, geosystems G³, 21(11), Article e2020GC009064. https://doi.org/10.1029/2020GC009064

We measured the concentrations of trace elements in Late Permian to Early Triassic sediments from Spitsbergen. High mercury concentrations in sediments from the level of the Permo-Triassic Mass Extinction (PTME) at this location were previously attri...

Size variations in foraminifers from the early Permian to the Late Triassic: Implications for the Guadalupian-Lopingian and the Permian-Triassic mass extinctions (2020)
Journal Article
Feng, Y., Song, H., & Bond, D. P. (2020). Size variations in foraminifers from the early Permian to the Late Triassic: Implications for the Guadalupian-Lopingian and the Permian-Triassic mass extinctions. Paleobiology, 46(4), 511-532. https://doi.org/10.1017/pab.2020.37

The final 10 Myr of the Paleozoic saw two of the biggest biological crises in Earth history: the middlePermian extinction (often termed the Guadalupian–Lopingian extinction [GLE]) that was followed 7–8 Myr later by Earth's most catastrophic loss of d...

Migration controls extinction and survival patterns of foraminifers during the Permian-Triassic crisis in South China (2020)
Journal Article
Benton, M. J., Liu, X., Song, H., Bond, D. P., Tong, J., & Benton, M. (2020). Migration controls extinction and survival patterns of foraminifers during the Permian-Triassic crisis in South China. Earth-Science Reviews, 209, Article 103329. https://doi.org/10.1016/j.earscirev.2020.103329

The Permian-Triassic mass extinction, the greatest biotic crisis in Earth history, triggered the complete replacement of ecosystems with the 5–10% surviving species giving rise to the Mesozoic fauna. Despite a long history of systematic studies on Pe... Read More about Migration controls extinction and survival patterns of foraminifers during the Permian-Triassic crisis in South China.

Late Ordovician mass extinction caused by volcanism, warming, and anoxia, not cooling and glaciation (2020)
Journal Article
Bond, D. P., & Grasby, S. E. (2020). Late Ordovician mass extinction caused by volcanism, warming, and anoxia, not cooling and glaciation. Geology, 48(8), 777-781. https://doi.org/10.1130/G47377.1

The Ordovician saw major diversification in marine life abruptly terminated by the Late Ordovician mass extinction (LOME). Around 85% of species were eliminated in two pulses 1 m.y. apart. The first pulse, in the basal Hirnantian, has been linked to... Read More about Late Ordovician mass extinction caused by volcanism, warming, and anoxia, not cooling and glaciation.
