Cryogenian (Geological periods 🌍)

The Cryogenian is a geologic period that lasted from 720 to 635 million years ago. It is the second of the three periods of the Neoproterozoic era, preceded by the Tonian and followed by the Ediacaran. The Cryogenian was a time of drastic climate changes. After the long environmental stability/stagnation during the Boring Billi...

Tonian (Geological periods 🌍)

The Tonian is the first geologic period of the Neoproterozoic Era. It lasted from 1000 to 720 Mya. Instead of being based on stratigraphy, these dates are defined by the ICS based on radiometric chronometry. The Tonian is preceded by the Stenian Period of the Mesoproterozoic Era and followed by the Cryogenian. Rifting leading to the breakup of supercontin...

Life on Earth was more diverse than classical theory suggests 800 million years ago, a Brazilian study shows

According to an article published in the journal PNAS, different lineages of #amoebae and ancestors of #plants, #algae and animals were already established in the #Neoproterozoic period and survived the two glaciations that covered the entire planet.

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...

Molecular fossils study sheds light on feeding strategy shift in ancient life https://phys.org/news/2023-12-molecular-fossils-strategy-shift-ancient.html

Common origin of sterol biosynthesis points to a feeding strategy shift in #Neoproterozoic animals https://www.nature.com/articles/s41467-023-43545-z

"these #phytosterol molecular #fossils record the rise of algae in ancient #oceans and #animals abandoned phytosterol production when they could easily obtain it from this increasingly abundant food source"
