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 …

Oceanic anoxia and extinction in the latest Ordovician
Abstract The Late Ordovician (Hirnantian) mass extinction (LOME) was marked by two
discrete pulses of high species turnover rates attributed to glacial cooling (LOME-1) and …
