The 'golden spike' Global Boundary Stratotype Section & Point for the *base* of the Ediacaran System, Flinders Ranges, Australia
#Ediacaran Period c. 635–541 Mya
from the end of global #Marinoan glaciation
to the first appearance worldwide of somewhat complicated trace fossils
#Ediacaran Period c. 635–541 Mya

The GSSP of the *upper* boundary of the #Ediacaran is the lower boundary of the #Cambrian

“Although the Ediacaran Period does contain soft-bodied fossils, it is unusual in comparison to later periods because its beginning is not defined by a change in the fossil record.”
“Although the Ediacaran Period does contain soft-bodied fossils, it is unusual in comparison to later periods because its beginning is not defined by a change in the fossil record.”
Instead it is defined at the base of a chemically distinctive Carbonate layer (bed) referred to as a "cap carbonate" because it caps glacial deposits
The bed is characterized by an unusual depletion of 13C that indicates sudden climatic change at the end of the #Marinoan ice age

#Marinoan Glaciation
from approximately 650 to 635 Mya during the #Cryogenian period
The glaciation may have covered the entire planet, in an event called #SnowballEarth
The end of the glaciation may have been sped by the release of Methane from *equatorial* permafrost…

“We shall not all sleep, but we shall all be changed - in a moment, in the twinkling of an eye - at the last trumpet.
For the trumpet will sound, and the dead will be raised incorruptible”
I Corinthians 15:51-52
in Latin as “in ictu oculi.”

#Metazoa
multicellular eukaryotic organisms that form the biological kingdom #Animalia
“animals consume organic material, breathe oxygen, move, reproduce sexually, and grow from a hollow sphere of cells, the #Blastula, during embryonic development”

#Eukaryotes
organisms whose cells have a nucleus enclosed within a nuclear envelope
The three domains of Life are #Bacteria and #Archaea (together known as #Prokaryotes) and #Eukaryota
Eukaryotes evolved approximately 1.6–2.1 billion years ago, during the #Proterozoic eon

#Proterozoic - a geological eon spanning the time from the appearance of Oxygen in Earth's atmosphere to just before the proliferation of complex life such as #Trilobites
The Eon extends from 2500 mya to 541 mya and is the most recent part of the #PreCambrian "supereon."
