It's all bio/chemo stratigraphy and geochron. But we didn't do any of the dating; all of these formations have been dated previously in the literature (and summarized in our supplement)

This provides new insights into the fundamental connections between (marine) biogeochemistry, planetary evolution, and life @eth-eaps.bsky.social @ethz.ch (and too many co-authors to list here)

There's been a lot of (model-based) hype over the years about a "large Neoproterozoic DOC reservoir" that could have triggered the end of snowball earth and the proliferation of multi-cellular life. BUT here we show this was not the case. Instead, DOC levels were about 90% lower than today

To defend the authors a bit, they do suggest doing this at an industrial rather than individual scale, but I still agree with your point
