## Where it stands

**Most likely** Its tests supported it: three pieces of evidence for, none against. It needs two reviews to be accepted.

## What it predicts

- Re-dating with all available samples spreads the layer ages over centuries.
- Many sites lack dates on or near the layer.

## What would rule it out

- Independent re-dating of the key sites converges on one century.
