Ediacaran: Biota, Ediacaran vs. Vendian & Upper and lower boundaries

The Ediacaran ( /ˌiːdiˈækərən, ˌɛdi-/ EE-dee-AK-ər-ən, ED-ee-) is a geological period of the Neoproterozoic Era that spans 96 million years from the end of the Cryogenian Period 635 million years ago to the beginning of the Cambrian Period 538.8 million years ago. It is the last period of the Proterozoic Eon as well as the last of the so-called…
