[QUOTE="essentialsaltes, post: 76128989, member: 294566"] [URL='https://www.washingtonpost.com/world/2021/07/29/fossils-canada-sponge-animals/']A geologist may have uncovered the oldest sign of animal life on Earth: sponge fossils that potentially date back 890 million years. That’s some 350 million years earlier than the oldest undisputed findings of animal fossils.[/URL] Elizabeth Turner, a professor at Laurentian University in Ontario, chanced upon the fossilized structures in rock formations while doing field work as a graduate student in the country’s remote northwest more than two decades ago. Examined under a microscope, the tiny sections of rock Turner uncovered contain a meshwork of three-dimensional structures — branching out in a distinctive way and rejoining — that closely resembles modern sponge skeletons.
