TL;DR: Combined microtomography, geochemistry, and sedimentary analysis suggest a biota fossilized during early diagenesis follows a rise in atmospheric oxygen, consistent with the idea that surface oxygenation allowed the evolution and ecological expansion of complex megascopic life.

Laser Raman micro-spectroscopy of Proterozoic and Palaeozoic organic-walled microfossils (acritarchs and prasinophytes) from the Ghadamis Basin, Libya and Volta Basin, Ghana

TL;DR: Laser Raman microspectroscopy was used as a microchemical analysis technique to characterize the wall chem- istry of organic-walled microfossils (acritarchs and prasinophytes) extracted from Proterozoic and early Palaeozoic marine sediments in the Volta Basin of Ghana, and the Ghadamis Basin of Libya, re- spectively as mentioned in this paper.
