Evidence is shown for: extinction rates (both as “global events” in which the bar width represents the magnitude of the extinction events, and as Columbia River (USA) Ethiopian Brito-Arctic Deccan (India) Rajmaha (India) Serra Geral (S. America) South-West Africa Antarctica South Africa E. North America Siberia Plate tectonics Impact structures Tethys closed Laurasia dispersed North Atlantic opened Gondwana dispersed Central Atlantic opened South Atlantic opened Tethys opened Dispersal of Pangaea PANGAEA Central lapetus closed North Atlantic closed Assemblage of Laurentia + Fennosarmatia Iapetus opened RODINIA high levels of volcanic eruptions, and changes in the shape of continents due to plate tectonic movements. Several periods of elevated extinction rates are associated with changes in sea level. Falls in sea level reduce the habitat available for marine life, driving species extinct. Changes in sea level will also be correlated with changes in climate. The combined influence of climate and sea level is widely thought to have contributed to some mass extinctions. However, sea level changes also occur at times when there is no Caledonian–Variscan megacycle Alpine megacycle 79 33 Piles Poplga 64 75 105 54 44 Kara 43 95 9 15 30 59 80 76 84 17 18 16 58 90 Sillan 91 97 Chicxulub structure Puchezh- Kalungi Manicouagan Diameter (km) 20–29 30–39 40–49 ranges 50–79 80–100 Age percentage rates, similar to Figure 23.2), sea levels, volcanic activity, plate tectonics, and asteroid impacts. The date of the end-Triassic volcanic rock has been updated from the source. (10 miles = 16 km.) Modified, by permission of the publisher, from Morrow et al. (1996). ..
