- Pulse of atmospheric oxygen during the late Cambrian - PNAS
Here we document a significant increase in atmospheric O 2 during the later Cambrian and examine the impact this may have had on biological evolution
- Pulses of atmosphere oxygenation during the Cambrian radiation of . . .
Significantly, evidence from this interval infers an oxygenation event in the backdrop of the most rapid radiation stage (ca 520 to 510 Ma) during the Cambrian explosion, confirming that oxygen availability was a crucial factor in accelerating the radiation of marine animals
- Pulse of atmospheric oxygen during the late Cambrian - PMC
Here we document a significant increase in atmospheric O 2 during the later Cambrian and examine the impact this may have had on biological evolution
- Pulse of atmospheric oxygen during the late Cambrian
We present concentration and isotope data for sedimentary mercury (Hg) and osmium (Os) to assess the impact of subaerial and submarine volcanism and weathering during the late Cambrian and
- Pulse of atmospheric oxygen during the late Cambrian - JSTOR
Here we document a significant increase in atmospheric O2 during the later Cambrian and examine the impact this may have had on biological evolution Beginning in the later parts of the Cambrian and continuing through much of the Ordovician, a series of complex, diachro-
- The Cambrian explosion’s spark | Stanford Report
Cambrian animals likely did not require as much oxygen as scientists used to believe We found minor increases in oxygenation that are at the correct magnitude to drive big changes in ecology
- Small change in Earth’s oxygen levels may have sparked huge . . .
By conducting a comprehensive, large-scale data analysis, researchers have identified just a small increase in atmospheric oxygen at the time of the Cambrian explosion "Cambrian animals likely did not require as much oxygen as scientists used to believe
- SALTZMAN, Matthew R. et al. Pulse of atmospheric oxygen during the late . . .
A significant rise in atmospheric oxygen during the late Cambrian likely influenced biological evolution The SPICE event produced approximately 19 × 10^18 moles of O2, raising levels to near 28%
- Pulse of atmospheric oxygen during the late Cambrian
We estimate that this organic carbon and pyrite burial event added approximately 19 x 1018 moles of O 2 to the atmosphere (i e , equal to change from an initial starting point for O2 between 10-18% to a peak of 20-28% O2) beginning at approximately 500 million years
