List of fossil dating methods - The Carbon Underground 200 2017 Edition | Fossil Free Indexes


The history of life on Earth began about billion years ago, during the Archean era, initially with single-celled prokaryotic cells, such as bacteria. Multicellular life evolved over a billion years later and it's only in the last 570 million years that the kind of life forms we are familiar with began to evolve, starting with arthropods , followed by fish 530 million years ago (Ma), land plants 475Ma and forests 385Ma. Mammals didn't evolve until 200Ma and our own species, Homo sapiens , only 200,000 years ago. So humans have been around for a mere % of the Earth's history.

The relationships of these taxa are often hard to determine, as many are known only from very fragmentary remains and due to the complete fossilization precluding analysis of information from DNA , RNA or protein sequencing. The taxa listed in this article should be classified with the Wikipedia conservation status category "Fossil".
