Ediacaran Fauna
Ediacaran fauna is a group of animal species that existed during the Ediacaran period, just before the Cambrian. The oldest Ediacaran fossils are about 570 million years old. Ediacarans included diverse species that looked like fronds, geometrical disks, and blobs covered with tire tracks. They appear to have become extinct 540 million years ago, although some researchers argue that certain Ediacaran taxa belong to extant animal clades.
