If you take a breath today remember to be grateful to the bottom of your lungs to these guys that made it all possible. Ice-polished ~1.5 billion yo Proterozoic fossil cyanobacterial stromatolite pavement, at Grinnell Glacier, Glacier NP, MT. Oldest fossils I have ever seen!

Quantifying the global biodiversity of Proterozoic eukaryotes
The global diversity of Proterozoic eukaryote fossils is poorly quantified despite its fundamental importance to the understanding of macroevolutionary patterns and dynamics on the early Earth. Here w...

New preprint out! Using ~75k environmental OTUs + 77 fossil calibrations, we reconstructed a Proterozoic timeline of eukaryote evolution. Our results show crown eukaryotes were already diversifying >1.6 Ga, long before the first undisputed fossils (~1.05 Ga).

They've turned the reflecting pool into a proterozoic diorama
This is so funny man. They were just repainting this like last week to make it look like a swimming pool and it's already straight up bong water
Friend sent me this photo he took today of the Reflecting Pool

I'm not here to Monday-morning-quarterback the choices of the Proterozoic Eon, but maybe gender was a mistake.
the reason he wants to bomb iran is because its penis to bomb things and vagina to be against bombing things, i know its stupid but it really is that simple
“[Trump] has not explained why he has chosen this moment to confront Iran instead of, for example, North Korea, which in the years after Mr. Trump’s failed negotiations in the first term has expanded its nuclear arsenal to 60 or more warheads”

#FossilFriday: a glacial erratic cobble of stromatolite, a fine algal carbonate rock, found at Cape Flinders, Kiillinnguyaq (Kent Peninsula), Nunavut, Canada, its source and age (probably Proterozoic?) unknown.

#FossilFriday falls with the creeping inevitability of a global glaciation. These Proterozoic stromatolites from Minnesota's Iron Ranges stand as a reminder that, no matter how small we are alone, together we can change the world, making complex relationships possible like a breath of fresh air. 🧪⚒️

I'm feeling pretty vindicated right now. I suggested this Fe + silica clay preservation model to a senior colleague to explain the exceptional preservation of my proterozoic and archean acritarchs. They dismissed me. The 3D acritarch I posted earlier is literally preserved in Fe-clay!
