Or M. BialikMicrobialites ( <a href="https://mastodon.world/tags/sedimentary" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sedimentary</a> buildups formed by microbial activity) were very common in the Proterozoic, but other groups took over in the Phanerozoic. But when the <a href="https://mastodon.world/tags/environment" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#environment</a> is stressed, they come back - and we can use them to infer on past <a href="https://mastodon.world/tags/ecological" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ecological</a> stress gradients, but also the conditions at the stressed end member. <a href="https://www.sciencedirect.com/science/article/pii/S0031018215005404" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.sciencedirect.com/science/article/pii/S0031018215005404</a> I rather like this paper, and to me, it's one of my most underperforming as far as citations are an index.

I love how it helps me educate and enthuse about geology! This one is of the limestone reef out at Castlepoint, North Island, NZ. These were connected once but sea erosion has separated them.
