A sulfidic driver for the end-Ordovician mass extinction
The end-Ordovician extinction consisted of two discrete pulses, both linked, in various ways,
to glaciation at the South Pole. The first phase, starting just below the Normalograptus …

Redox changes in the outer Yangtze Sea (South China) through the Hirnantian Glaciation and their implications for the end-Ordovician biocrisis
Two pulses of faunal mortality occurred during the Late Ordovician mass extinction (ca. 445
Ma). This biocrisis is recorded in Hirnantian strata of South China as a stepwise extinction of …
