英文摘要 | The role of oxygen as a driver for early animal evolution is widely debated. During the Cambrian explosion, episodic radiations of major animal phyla occurred coincident with repeated carbon isotope fluctuations. However, the driver of these isotope fluctuations and potential links to environmental oxygenation are unclear. Here we report high-resolution carbon and sulfur isotope data for marine carbonates from the southeastern Siberian Platform that document the canonical explosive phase of the Cambrian radiation from similar to 524 to similar to 514 Myr ago. These analyses demonstrate a strong positive covariation between carbonate delta C-13 and carbonate-associated sulfate delta S-34 through five isotope cycles. Biogeochemical modelling suggests that this isotopic coupling reflects periodic oscillations in the atmospheric O-2 and the extent of shallow-ocean oxygenation. Episodic maxima in the biodiversity of animal phyla directly coincided with these extreme oxygen perturbations. Conversely, the subsequent Botoman-Toyonian animal extinction events (similar to 514 to similar to 512 Myr ago) coincided with decoupled isotope records that suggest a shrinking marine sulfate reservoir and expanded shallow marine anoxia. We suggest that fluctuations in oxygen availability in the shallow marine realm exerted a primary control on the timing and tempo of biodiversity radiations at a crucial phase in the early history of animal life. |
