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

Siderian (Geological periods 🌍)

The Siderian Period is the first geologic period in the Paleoproterozoic Era and lasted from 2500 Ma to 2300 Ma. Instead of being based on stratigraphy, these dates are defined chronometrically. The deposition of banded iron formations peaked early in this period. These iron-rich formations were formed as anaerobic cyanobacteria produced waste oxy...

#ExtinctionLevelEvent

Yes, the only other species known to me to have ever been so stupid as to have destroyed their whole biosphere on a global level, are #cyanobacteria in the #GreatOxidationEvent in the #Paleoproterozoic Era.

2.4 billion years and #humanity collectively has an #IQ of these ancient bacteria.

Maybe, it deserves to become extinct?

Cheers!

Orosirian (Geological periods 🌍)

The Orosirian Period is the third geologic period in the Paleoproterozoic Era and lasted from 2050 Mya to 1800 Mya. Instead of being based on stratigraphy, these dates are defined chronometrically. The later half of the period was an episode of intensive orogeny on virtually all continents. Two of the largest known impact events on Earth occurre...

Complex life on Earth began around 1.5 billion years earlier than previously thought, new study claims https://phys.org/news/2024-07-complex-life-earth-began-billion.html

#Hydrothermal seawater eutrophication triggered local macrobiological experimentation in the 2100 Ma #Paleoproterozoic Francevillian sub-basin https://www.sciencedirect.com/science/article/abs/pii/S0301926824001669

The study describes an episode of unique underwater volcanic activity following the collision of 2 continents, which created a nutrient-rich laboratory for the earliest experiments in complex #evolution.

Dr Erica Barlow picked up a rock by chance 10 years ago. It might hold the oldest form of complex life on Earth https://news.unsw.edu.au/en/erica-picked-up-a-rock-10-years-ago-it-might-hold-the-oldest-form-of-complex-life-on-earth

Distinctive #microfossil supports early #Paleoproterozoic rise in complex cellular organisation https://onlinelibrary.wiley.com/doi/10.1111/gbi.12576

"the age estimate coincides with the #GreatOxidationEvent... The sharp rise of oxygen has been linked to the development of complex life on Earth, but we haven’t had the fossil record to demonstrate this – until now."

Rhyacian (Geological periods 🌍)

The Rhyacian Period is the second geologic period in the Paleoproterozoic Era and lasted from 2300 Mya to 2050 Mya. Instead of being based on stratigraphy, these dates are defined chronometrically.The Bushveld Igneous Complex and some other similar intrusions formed during this period.The Huronian global glaciation began at the start of the Rhyacia...

Statherian (Geological periods 🌍)

The Statherian Period is the final geologic period in the Paleoproterozoic Era and lasted from 1800 Mya to 1600 Mya. Instead of being based on stratigraphy, these dates are defined chronometrically.The period was characterized on most continents by either new platforms or final cratonization of fold belts. Oxygen levels were 10% to 20% of cur...
