[HTML][HTML] The end-Ordovician mass extinction: a single-pulse event?
G Wang, R Zhan, IG Percival - Earth-Science Reviews, 2019 - Elsevier
The end-Ordovician mass extinction (EOME) is widely interpreted as consisting of two
pulses associated with the onset and demise of the Gondwana glaciation, respectively, with …
