Major Fossil Localities

Use locality and formation as evidence while respecting legal, ethical, and site-protection obligations.

A place name should be specific enough to test.

Country alone is rarely sufficient. Good provenance may include region, county, quarry, formation, member, horizon, collector, date, and legal source.
