Decline and fall of the Ediacarans: late‐Neoproterozoic extinctions and the rise of the modern biosphere

Biological Reviews, Volume 99, Issue 1, Page 110-130, February 2024.
ABSTRACT The end‐Neoproterozoic transition marked a gradual but permanent shift between distinct configurations of Earth's biosphere. This interval witnessed the demise of the enigmatic Ediacaran Biota, ushering in the structured trophic webs and disparate animal body plans of Phanerozoic ecosystems.
