“Life was pretty nice during the Ediacaran, so the need for sex was rather limited,” said lead author Dr. Emily Mitchell from Cambridge’s Department of Zoology. “There was relatively little competition, so there was no real pressure to change anything.”
Kein Wunder, dass das mein liebstes Erdzeitalter ist.

"Led by Scott Evans, assistant curator of invertebrate palaeontology at the American Museum of Natural History, [the study] draws on rare 567-million-year-old fossils to show animal evolution may have started far earlier than previously thought. "

#Fossils reveal many complex #animals existed before the #CambrianExplosion
More than 539 million years ago, from the #Ediacaran Period, soft, clarinet-shaped animals anchored themselves to the seafloor on disc-shaped bases, swaying alongside stalked animals resembling worms and baskets. These woodwindlike creatures are just a few of those coming to life from a treasure trove of newly discovered fossils in southwestern #China.

Spectacular fossil treasure trove pushes back origins of complex animals https://www.ox.ac.uk/news/2026-04-03-spectacular-fossil-treasure-trove-pushes-back-origins-complex-animals
The dawn of the #Phanerozoic: A transitional fauna from the late #Ediacaran of Southwest China https://www.science.org/doi/10.1126/science.adu2291
"A newly discovered fossil site in southwest China has transformed our understanding of how complex animal life emerged on Earth, revealing that many key animal groups had already evolved before the start of the #Cambrian Period."

"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"

Hace 555 millones de años, en el Ediacárico, vivió la Kimberella quadrata, una extraña criatura de aguas someras de clasificación incierta, pero que pudo ser la antepasada de los moluscos. 📷Nobu Tamura #mollusca #ediacarico #ediacaran

Oh, AI -- is there anything you can't screw up? On the left, supposedly a picture of Ediacaran animal(?) Dicksonia costata, while on the right we have what they actually look like.
From the truly dreadful an*malsaroundth*gl*be.com, wot I just came across. Censored to prevent any possible automated cataloguing of the place.

Ediacaran (Geological periods 🌍)
The Ediacaran is a geological period of the Neoproterozoic Era that spans 96 million years from the end of the Cryogenian Period at 635 Mya to the beginning of the Cambrian Period at 538.8 Mya. It is the last period of the Proterozoic Eon as well as the last of the so-called "Precambrian supereon", before the beginning of the subsequent Cambrian P...

The study on Marine Life Evolution suggests that a weaker magnetic field in Earth’s past may have been a catalyst for significant changes in marine life during the Ediacaran Period. This finding links geophysical events with biological evolution and offers insights into the conditions that may foster life on other planets.
