How these dates were made
Why this bar's edges are floors, not a founding and a fall.
The atlas draws the world at 6 moments in time, not continuously. This bar runs from the first snapshot in which Guanahatabeyes appears to the last, so both edges are floors — the earliest and latest years it is attested, not a founding and a dissolution.
Elsewhere in Americas at the time
Records whose own span overlaps this one, found by the same test the canvas draws with. The bar under each card is where it sits inside this one.
