Kind: research · Impact: low

## In brief

- Geologists report new evidence that sea-level changes carved large underwater canyons in South Australia's Flinders Ranges hundreds of millions of years ago.
- The canyon formation is linked to conditions that helped preserve some of Earth's earliest complex life.
- The source summary is truncated, so further specifics of the study are not confirmed here.

## Why it matters

The findings connect past sea-level change and seafloor geology with the preservation of early complex life, which bears on how the fossil record of ancient animals is interpreted.
