'''Ediacara-faunaen''' eller '''Vendia-faunaen''' er forhistoriske livsformer, der repræsenterer de ældste kendte former for kompliceret flercellet liv på [[Jorden]].
 
De første spor efter Ediacara-faunaen er omtrent 600 millioner år gamle, men blomstrede først rigtigt op i en periode kaldet den Avalonske eksplosion (575 millioner år siden), der fulgte kort efter en voldsom [[Cryogenium|kuldeperiode]], der praktisk taget havde [[Sneboldjord|dækket hele jordkloden med is]]. I et 558 millioner år gammelt ''Dickinsonia''-fossil er der fundet fedtstoffet [[cholesterol]], som dermed gør ''Dickinsonia'' til det første dyr, der kendes.<ref>{{Cite web |url=https://www.sciencealert.com/dickinsonia-russia-white-sea-fossil-fat-cholesterol-molecules-confirm-animal |title=This Eerie Creature Was Just Officially Confirmed as The World's Earliest Known Animal.
