Whereas previous remnants were dated to 570 million years ago, this new evidence is 2.1 billion years old. The fossils were discovered in a deposit in Gabon, where the oldest multicellular organisms were found. The results appear in the 11 February 2019 edition of <i>PNAS<\/i>.<\/p>\n<p>A few years ago, geologist Abderrazak El Albani and his team at the Institut de chimie des milieux et mat\u00e9riaux de Poitiers (CNRS\/Universit\u00e9 de Poitiers) discovered the oldest existing fossils of multicellular organisms in a deposit in Gabon. Located in the Franceville Basin, the deposit allowed scientists to re-date the appearance of <a class=\"textTag\" href=\"https:\/\/phys.org\/tags\/multicellular+life\/\" target=\"_blank\" rel=\"noopener tag\">multicellular life<\/a> on Earth to 2.1 billion years\u2014approximately 1.5 billion years earlier than previously thought (600 million). At the time, the researchers showed that this rich biodiversity co-occurred with a peak in dioxygenation of the atmosphere, and developed in a calm and shallow marine environment.<\/p>\n<\/div>\n<p>In this same geological deposit, the team has now uncovered the existence of fossilised traces of motility. This shows that certain multicellular organisms in this primitive marine ecosystem were sophisticated enough to move through its mud, rich in organic matter.<\/p>\n<p>[ <a href=\"https:\/\/phys.org\/news\/2019-02-discovery-oldest-evidence-mobility-earth.html\">click to continue reading at physical.org<\/a> ]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>from Phys.org Discovery of the oldest evidence of motility on Earth &nbsp; Previously, the oldest traces of this kind found dated to approximately 600 million years ago: the Ediacaran period, also characterized by a peak in dioxygen and a proliferation in biodiversity.
