Exceptionally preserved 551-million-year-old site suggests #AvalonBiota lasted longer https://phys.org/news/2026-02-exceptionally-million-year-site-avalon.html paper: https://pubs.geoscienceworld.org/gsa/geology/article-abstract/doi/10.1130/G54217.1/725338/Ediacaran-endlings-from-the-Avalon-Assemblage-and

"That loss of diversity in the late #Ediacaran has long been recognized as the #KotlinCrisis, making it the first #extinction event that #animals ever experienced. The percentage of known macroorganisms that went #extinct at the Kotlin Crisis event is, in light of this newly published study, considered to be around 80%"

The Long and the Weak of It—The #Ediacaran Magnetic Field https://eos.org/articles/the-long-and-the-weak-of-it-the-ediacaran-magnetic-field

"Our planet’s magnetic field was remarkably weak then, and new research suggests that that situation persisted for roughly 3 times longer (70 million years) than previously believed. That negligible magnetic field likely resulted in increased atmospheric oxygen levels, which in turn could have facilitated the observed growth of macroscopic organisms"
