What is eoandromeda?

Eoandromeda is an animal genus from Ediacaran, dated about 550 million years ago. These animals are interesting because they seem to be the first adult animals in a fossil record, reflecting the main change throughout life on Earth. In fact, there is some debate on whether Eoandromeda belongs to the Kingdom of animals at all, and some of which say fossilized remnants can be the remains of algae. However, it seems that evidence strongly supports the idea that these remains are in animals, and if so, it means the main discovery.

Only one species in this family was discovered, eoandromeda octobrachiata , the octagonal organism shows radial symmetry. Of the fossils that remain, scientists assumed that the body had a dome -shaped body and that it was probably very simple, which shows a very gross step along the way to the development of animals that wander through the ground today, although the organism could be similar to jellyfish. It was probably a soft organism, due to the body structures modernthe deep creatures. It is known that it is known to be expected, given the limited fossil evidence and the limitation of animals that exist only in fossilized form.

Another interesting thing about Eoandromeda is that animals are preserved in two significantly different ways, protection of EDIACARAN and maintaining slate. Ediacaran preservation is a type of preservation in which fossils have been preserved by microbial mats on the bottom of the ocean, with microbes developing a thick film that protected the animal when it slowly disintegrated and then mineralized the rest of thece bottom. In the Burgess slate preservation, fossilized remnants are captured in remarkably clear detail in shale formations.

Two types of preservation maintain different structures, which made it difficult to confirm that scientists really looked at the same creature. The fact that examples of both types of maintenance can be found that Eoandromeda can be a key part of HistOrie fossil record and provides traces that could be used to identify and the date of other fossils.
