Non-free / fair use media rationale for Ediacara biota
Description	Doushantuo "embryo"
Source	Nature
Article	Ediacara biota

Purpose of use	This is an image of a structure believed (by some) to be an early embryo, which, if true, is vitally important to the evolution of the Ediacaran biota. Even with the dispute over the accuracy of the claims, they are an important part of scientific research into the Ediacaran biota, and there is no other way to really explain what the debate is about without showing them.
Replaceable?	Impossible without access to original material
