Iron probably didn’t rust much before Cyanobacteria.
Copper never turned green
Think about that…
Then the Cyanobacteria came in, and all the iron that surfaced during varying periods of time all rusted at once

WHAT: Winogradsky columns, initially and after 7 weeks WHEN: 2006 WHO: Tjmhay on Wikipedia
Microworld. This is a preview of this month's patreon phone wallpaper!! 🦠
I think this one's my favourite one so far and it's going on my own phone hehe ☺️
I've been learning about microorganisms for two days now and have grown deeply fascinated since wondering what the algae that my pink ramshorn snails eating, actually is 🐌
A very splendid Ricasolia virens lichen with a black, bushy thallus containing cyanobacteria and a scattering of bright green lobes with algae instead.
Scytinium turgidum
When I see people tag my lichen posts with #plant, I have to admit, a part of me dies inside. Because like, cyanolichens like S. turgidum have no plants parts. This guy is composed of an ascomycete fungi and a cyanobacteria -- no plants involved whatsoever. This jelly lichen grows on calcareous rock often inundated with runoff. It has shiny red-black to blackish-olive lobes which are wrinkled and thin when dry, thick and gelatinous when wet. The upper surface is covered in granular isidia, and often brownish-red apothecia. S. turgidum has a Nostoc photobiont.

It's crazy to think that going to a beach on a nice sunny day on earth looked like this 2.8 billion years ago.
The orange sky is not a sunset. There's little to no oxygen in the air so the ozone layer didn't exist yet.
The only life that existed was bacteria and archaea in a green ocean.
About 2.4 billion years ago, oxygen-making bacteria changed Earth forever. Their oxygen poisoned many early microbes and helped destroy methane, a warming gas. That may have helped trigger long Snowball-Earth-like ice ages that lasted, with warmer breaks, around 300 million years.
