Rapid marine oxygen fluctuations linked to climate-driven weathering during the Late Ordovician Mass Extinction
The Late Ordovician Mass Extinction (LOME) comprised two pulses of biodiversity loss under contrasting climatic conditions, yet how these transitions reshaped marine redox conditions remains enigmatic. Here we present paired carbonate cerium isotope (δ142Ce) and neodymium isotope (δ146Nd) records from an Upper Ordovi...
