Here we use palynology coupled with high-precision CA-ID-TIMS dating of euhedral zircons from continental sequences of the Sydney Basin, Australia, to show that the collapse of the austral Permian Glossopteris flora occurred prior to 252.3 Ma (~370 kyrs before the main marine extinction). Weathering proxies indicate that floristic changes occurred during a brief climate perturbation in a regional alluvial landscape that otherwise experienced insubstantial change in fluvial style, insignificant reorganization of the depositional surface, and no abrupt aridification. Palaeoclimate modelling suggests a moderate shift to warmer summer temperatures and amplified seasonality in temperature across the EPE, and warmer and wetter conditions for all seasons into the Early Triassic. The terrestrial EPE and a succeeding peak in Ni concentration in the Sydney Basin correlate, respectively, to the onset of the primary extrusive and intrusive phases of the Siberian Traps Large Igneous Province. #------------------ # Funding_Agency # Funding_Agency_Name: US National Science Foundation # Grant: EAR-1636625 #------------------ # Site_Information # Site_Name: Pacific Power Hawkesbury Bunnerong DDH-1 # Location: Australia/New Zealand>Australia # Country: Australia # Northernmost_Latitude: -33.976 # Southernmost_Latitude: -33.976 # Easternmost_Longitude: 151.218 # Westernmost_Longitude: 151.218 # Elevation: #------------------ # Data_Collection # Collection_Name: BunnerongPermo-Triassic # Earliest_Year: 259000000 # Most_Recent_Year: 248000000 # Time_Unit: Cal.
