## Where it stands

**Disputed** One piece of evidence for, none against. It needs two reviews to be accepted.

## What it predicts

- New texts read coherently with the 1993 values.
- Grammatical morphemes read on La Mojarra match reconstructed proto-Zoquean.

## What would rule it out

- A substantial new text yields no coherent reading with the values fixed in 1993.

## Evidence 1 for · none against

[A column noticed in 1995, after the decipherment, read readily with the 1993 values.](https://mysteriesdept.com/mysteries/cascajal-block/evidence/EVD0CYBC5YM6NG6/a-column-noticed-in-1995-after-the-decipherment-read-readily)
