Biological fossil discovery 545 million years ago

Scientists from the Argentine Geological Research Center (CIG) have found fossils of living organisms that lived 545 million years ago in the city of Olavarría.

545 million-year-old fossil was found in Argentina.

According to a reporter in Argentina, experts have not identified the fossils as animals or plants. However, this is an important discovery. Because in that era, the only organism that existed was only living single-celled algae floating in the water. Hundreds of fossils found on rocks are organisms (including animals, plants and other species) living in a certain area 545 million years ago. CIG evaluates these creatures as the oldest fossil record in South America.

CIG expert Maria Julia Arrouy expresses the impression of a structured creature that has not been identified as an animal or plant in that era. Maria said that the scientific community agreed that these were the first and oldest living things in the Earth history of the Ediacara Era that lasted about 635 to 542 million years ago. Geologists have found "fossil bodies" that are more complex than normal, formed by eukaryotic cells, such as membranes, cytoplasm, nuclei and tissue.

These fossils are very rare in the world, appearing only in Canada, Australia, Namibia, China, Russia and the United Kingdom. Experts believe that the fossils found in the city of Olavarría are the oldest in the Ediacara period discovered so far and they belong to the group of marine creatures in the Ediacara period.
