Newest oldest fossils found

leave a comment »

Very interesting article by Becky Ferreira in Motherboard. It begins:

he oldest fossils in the entire goddamn record have been found in Greenland’s Isua Greenstone Belt, according to new research published Wednesday in the journalNature. These fossils advance our understanding of how and when life formed on our planet, and the role it played in shaping the planet’s biosphere.

Forged by cyanobacteria some 3.7 billion years ago, these layered sedimentary formations, called “stromatolites,” push the timeline of confirmed life on Earth back by a full 220 million years. The previous record-holder, the well-known 3.5-billion-year-old stromatolites of Western Australia, has now been unseated by a wide temporal margin. . .
