The first animals evolved towards the end of the Ediacaran period, around 580 million years ago. However, the fossil record shows that after an initial boom, di...
Ancient microorganisms found in halite may have implications for search for life
May 12, 2022 (SPX)
As halite crystals grow in saline surface waters, it traps parent water in primary fluid inclusions. In addition to trapping parent waters, they can trap any so...
Massive carbon emission caused marine anoxia and biodiversity loss 304M years ago
