The third and final era of the Proterozoic eon, spanning 1 billion to 538.8 million years ago and closing the Proterozoic. It includes the Cryogenian's severe Snowball Earth glaciations and the Ediacaran's rise of the Ediacaran biota, the first widespread fossil evidence of complex multicellular animal life, setting the stage for the Cambrian explosion.
