What are the oldest macroscopic fossils?

The oldest macroscopic fossils of the body date back to the ancient Ediacaran period, which expanded 635 to 542 million years ago. The oldest known megafosil side is Twitya formation in the Mackenzie Makers in Northwest Canada with fossils from 610 to 600 million years. The extreme age of these fossils is truly remarkable: putting things in a perspective, for more than a hundred years it was assumed that the Cambrian period (542 million years ago) contained the oldest multicellular fossils. Until 1957, until it was realized that a complex life could be a few million years ago several million years ago. Another oldest is the Drook formation from Southeast Newfoundland with an estimated age of 595 to 565 million years. Megafosily Twitya and Drook have similarity to Cnidarians - sea pens - quilted, double -sided queues similar to D -like, similar to ferns in appearance. These animals, known as Charnia , were pre -classified as related to Cnidarians, becauseE CNIDARIANS are the oldest known metazoans (multicellular organisms) and most paleontologists are loss to describe these mysterious fossils.

Sometimes Charnia is quoted as "Metazoan of the complexity of the Cnidarian class". It is named after the English Forest Charnwood, where it was first discovered. Charnia is the best known megafosil period Ediacaran, so long-living-Fossil were dated until 520 million years ago, 20 million years after the Ediakar Cambrian border. So the existence of Charnia was obviously up to 90 million years.

6ion has sometimes ruled out from the "Ediacaran Fauna" class because of its simplicity. The confusion is sometimes caused because it is discussed whether such simple impressions are actually independent animals or rather colonies of unicellular organisms.

Twitya formation is particularly unique in all fossil sites because it precedes the Varangians-MarinoanIce crazy, which occurred between 600 and 585 million years. This attack is often quoted as a barrier that detained the formation of a complex multicellular life, although we can say from the creation of Twitya that this is not true. It is true that Twitya formations include only relatively simplistic fossils, but are truly macroscopic and very likely multicellular.

Twitya fossils include a number of segmented worms, leaves, discs and immobile bags, as well as probable Holdsfasts and trace fossils. These are collectively known as the Fauna Ediacaran and are One of the most interesting categories of life ever lived. They are considered the first experiments of life in multicellularity.
