The reason why stromatolites rebounded to levels higher than before the end other burrowing organisms went extinct.

  • When extinction was about to take place in Pemian, about two-thirds of marine animals were sessile and attached to the seafloor.

The Permian extinction witnessed Lowered sea levels and volcanic fallout. This shows that much higher levels of carbon dioxide was present in the oceans, that has caused the collapse of marine ecosystems.

The formation environment of stromatolites is linked with tidal plains of shallow, brackish, relatively calm, warm waters of good luminosity with the presence of weak currents.

There was known to be a low level of predation, as a lot of organisms were extinct and the environment may have been hypersaline.
