- •
Eurypterid–evaporite occurrences in the Appalachian basin were examined.
- •
In a single eurypterid assemblage survey, 2% of specimens contained cross-cutting evaporites.
- •
In a regional survey, 37% of eurypterid-bearing intervals contained salt hoppers.
- •
A depositional model explains the frequent eurypterid–salt hopper associations.
- •
Results refute the traditional view that eurypterids were halotolerant organisms.
