The Avalon assemblage was the first of the three Late Ediacaran biotic assemblages, spanning from c. 575 Ma to c. 560 Ma. It was followed by the White Sea assemblage, although temporal overlaps have been noted between the biotic assemblages. While earlier macroscopic fossils, mostly of algal origin, are known from the Lantian Formation, Avalon-type localities provide some of the first evidence of putative metazoan ancestors, as part of the Ediacaran biota.
