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 …

Nov 08, 2022 · The Ediacaran Period marks the first time multicellular life was widespread on the planet. It predates the more well-known Cambrian Period, when more complex life emerged, diversified, and flourished.

Jun 16, 2022 · Multicellularity. In the Neoproterozoic era, particularly in the Ediacaran period (around 600 million years ago), the first multicellular form emerged.How multicellularity came about is still a matter of debate until now. The most popular theory in …

El período Ediacárico o periodo Ediacarano (en referencia a las montañas Ediacara), una división de la escala temporal geológica, es el tercer y último período geológico de la era Neoproterozoica.Comienza hace unos 635 millones de años y finaliza hace 542,0 ±1,0 millones de años (es seguido por el Cámbrico).Las fechas se han fijado sobre la base de criterios de …

The Eocene (/ ˈ iː ə s iː n, ˈ iː oʊ-/ EE-ə-seen, EE-oh-) Epoch is a geological epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period in the modern Cenozoic Era.The name Eocene comes from the Ancient Greek ἠώς (ēṓs, "dawn") and καινός (kainós, "new") and refers to the "dawn" of modern ('new') fauna that appeared ...

Phanerozoic and the Ediacaran; only GSSPs do. For boundaries in the Phanerozoic without ratified GSSPs or without constrained numerical ages, an approximate numerical age (~) is provided. Ratified Subseries/Subepochs are abbreviated as U/L (Upper/Late), M (Middle) and L/E (Lower/Early). Numerical ages for all systems except

The Late Pleistocene is an unofficial age in the international geologic timescale in chronostratigraphy, also known as Upper Pleistocene from a stratigraphic perspective. It is intended to be the fourth division of the Pleistocene Epoch within the ongoing Quaternary Period. It is currently defined as the time between c. 129,000 and c. 11,700 years ago. The Late …

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 …
