🦴🎸 Scientists at Memorial University of #Newfoundland renamed ancient seafloor #fossils "Lydonia jiggamintia" after punk rocker Johnny Rotten, identifying them as 560-million-year-old filter-feeding #animals rather than decomposed organic matter. The spiky, tube-covered creatures may be ancestors of modern sponges and represent some of #Earth's earliest animals from the #Precambrian period.

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."

For years I've been keeping an eye on the disputed Francevillian biota -a possible experiment in multicellular life that well pre-dated the Ediacaran/Cambrian foray we all see today.

Recently we got a new paper on the subject suggesting that it existed in an inland sea cut off from the wider world, which prevented it from thriving and led to its extinction when O2 levels in the atmosphere went south again:

No free version, unfortunately, until 2025.

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.
