The Ediacaran Period (/ iː d i ˈ æ k ər ə n, ɛ d i-/ ee-dee-AK-ər-ən, ed-ee-) is a geological period that spans 96 million years from the end of the Cryogenian Period 635 million years ago (Mya), to the beginning of the Cambrian Period 538.8 Mya. It marks the end of the Proterozoic Eon, and the beginning of the Phanerozoic Eon.It is named after the Ediacara Hills of South Australia.

The Ediacaran (/ ˌ iː d i ˈ æ k ər ə n /; formerly Vendian) biota is a taxonomic period classification that consists of all life forms that were present on Earth during the Ediacaran Period (c. 635–538.8 Mya).These were composed of enigmatic tubular and frond-shaped, mostly sessile, organisms. Trace fossils of these organisms have been found worldwide, and represent the …

Ediacara fauna, also called Ediacara biota, unique assemblage of soft-bodied organisms preserved worldwide as fossil impressions in sandstone from the Ediacaran Period (approximately 635 million to 541 million years ago)—the final interval of both the Proterozoic Eon (2.5 billion to 541 million years ago) and Precambrian time (4.6 billion to 541 million years ago).

Polymetallic nodule fields are hotspots of abundance and diversity for a highly vulnerable abyssal fauna, much of which lives attached to nodules or in the sediment immediately beneath it. Nodule mining could affect tens of thousands of square kilometers of these deep sea ecosystems, and ecosystems take millions of years to recover.

Ediacaran Period, also called Vendian Period, uppermost division of the Proterozoic Eon of Precambrian time and latest of the three periods of the Neoproterozoic Era, extending from approximately 635 million to 541 million years ago. The Ediacaran followed the Cryogenian Period (approximately 720 million to approximately 635 million years ago) and was succeeded …

Precambrian, period of time extending from about 4.6 billion years ago (the point at which Earth began to form) to the beginning of the Cambrian Period, 541 million years ago. The Precambrian encompasses the Archean and Proterozoic eons, which are formal geologic intervals that lasted from 4 billion to about 541 million years ago, and the Hadean Eon, which is an informal interval …
