What are some EDIACAAN organisms?

Ediacaran Organisms lived during the Ediacaran period, a geological period ranging from approximately 635 to 542 million years. Ediacaran first includes the well -known occurrence of multicellular organisms that begin to appear in a fossil record 600 million years ago with small Cnidarians (related jellyfish and corals), porifers (mushrooms) and early bilateral animals such as vernanimalcula .

Fossilized Ediacaran Organisms Fall into Two Categories: The So-Called Ediacaran Fauna, A Range of Quilt and Bag-Like Forms Sometimes Called "Life's Failed Experiment" Early Examples of Animals that Continumed Into the Cambrian (Immmediales After the Ediacaran Period) and Beyond, WHICH INCLUDES CNIDARIANS, PORIFERANS, and soon bilatrices such as segmented worms. Sometimes confusing the word "eDiacaran fauna" refers to all organisms living during the edition period, while other Times only concerns initial carriageMultime -cell organisms with a distinctive quilted look. Some Cladists even classify them in their own kingdom in the eukaryota domain. The relationship of Edicaranian organisms to current forms is very much discussed. Although no one has ever claimed that chords (animals with spine or Notocord) can be found in the fossil EDIACAN recording, it is said that phyles such as molluscs, Annelids, Flatworms, Nematodes and others could have occurred during this time.

One of the iconic organisms Ediacaran is dickinsonia , a bilaterally symmetrical ribbed oval of unknown affinity. dickinsonia ranged from 4 to 1400 millimeters, very high degree of view. It is assumed that he showed unlimited isometric growth, that is, it is constantly growing until he died. The dickinsonia internal fibers consist of 0.5-1 mm spindle fibers in diameter of unknown functions.

Another iconic orgaNism Ediacaran, Yorgia , looked like a hybrid between dickinsonia and a segmented worm. Very long trails from Yorgia were found, in the range of up to 43 m (141 ft), which strongly indicates that the organism was mobile.

One of the famous Ediacaran organisms was Charnia , an animal similar to the people, whose discovery in 1957 caused the scientific community for the first time to take the idea of ​​ancestor of multicellular life for the first time. Charnia , some of which exceed the length of 2 m (6.5 ft), is temporarily and geographically the most widespread fossil Ediacaran. Although this interpretation was initially classified as a relative of a sea pen, it has been discredited since then.
