My nine-year-old is complaining because their natural history books don't have enough to say about the Ediacaran Period. Naturally, I turn to fedi for suggestions of resources I can point them at. Any thoughts? We already listen to the Common Descent podcast.

@KateShaw has made a new episode, featuring goblet-shaped Diskagma of the Paleoproterozoic, and Horodyskia of the Mesoproterozoic and Neoproterozoic.

First evidence of life colonizing deep into the bedrock of Greenland https://phys.org/news/2024-09-evidence-life-colonizing-deep-bedrock.html

Late #Cretaceous and Early #Paleogene Fluid Circulation and Microbial Activity in Deep Fracture Networks of the #Precambrian Basement of Western Greenland https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2024GC011646

"These ages overlap with tectonic events related to the opening of the Atlantic Ocean... deep fracture networks in western #Greenland opened and were colonized by #microbes, such as sulfate reducers, during these events."

An awesome present from Australia - a lump of Proterozoic banded ironstone from the Marra Mamba Iron Formation (Hamersley region, Pilbara Craton, WA) - 2.4 billion years old.

TIL that the first pre-#cambrian #fossil, Charnia masoni, was originally discovered by a 15 years old girl named Tina Negus, who was discounted by her geography teacher saying precambrian fossils were impossible.
A year later it was rediscovered by a boy named Roger Mason, who also took a stone rubbing of the fossil. This time the discovery was taken seriously, and the species is even named "masoni" to this day after him.

A sprinkling of #snow made for a beautiful #sunset on the crags and Jewels Hill rocks of Beacon Hill (which are #SSSI & #Precambrian) #LOUGHBOROUGH this evening
