What is the Ediacaran period?

The

Ediacaran period (named after Ediara Hills in South Australia, where fossils from this period were found) is a geological period between about 635 and 542 million years ago. In the edition of Ediacaran, the first macroscopic multicellular fossils, dated up to 610 million years ago (Twitya formation), are the most diverse communities concentrated around 575 - 542 million years. The anticipated fossil embryo was dated to the Dawn of Ediacaran, 632.5 million years ago. This Ice Age, which spread 745 to 635 million years ago, was so extreme that the period before Ediacaran is called the cryogenic period after the Greek "Cryo", which means "cold". Some scientists believe that the world's oceans have gone through almost complete freezing episodes during this period, led to the "snowball" of the scenario. Deposits from glaciers were found in equatorial latitudes. Life could survive in refugia, such as the deep hydrothermal openings. The division between Ediacaran and Cryogenan is a time when they finally end upLa era.

Although life in the form of microbes has existed from at least 2.7 billion years ago and microbes with cores (eukaryotes) existed from 1.2 billion years, Ediacaran is the first unnecessary fossils of multicellular life. This family of life, "Ediacaran Fauna", consists of different plant animals unknown affinity with a quilted look, with the form of leaves, discs, bags and "inflated mattresses". Together with the Ediacaran Fauna, some precursors of modern phyla, such as trilobite-like Spriggina , lived, which are not generally considered during the Ediacaran period. “It is confusing, but the term“ Ediacaran ”is also used to refer to a different grouping of ancient organisms and the geological period itself.
