Campanian
Fifth Late Cretaceous age, named for the Grande Champagne of Charente, not Italy’s Campania.
Language and route: Scientific French from French regional toponym Champagne. French Champagne (the Grande Champagne of Charente) → Campanien → English Campanian; not Campania in Italy.
Literal gloss: ‘of/from Grande Champagne / Champagne charentaise near Cognac’ (geographical; not a Greek compound)
The name and its history
Henri Coquand · 1857; geographical justification 1858
- What does the word literally mean?
- ‘of/from Grande Champagne / Champagne charentaise near Cognac’ (geographical; not a Greek compound)
- What did the original author mean?
- Coquand applied Campanian to chalk and marly limestones of the Grande Champagne region, correlating them with the chalk of the Paris Basin.
- Why was the name needed?
- The older Senonian and local Upper Chalk subdivisions did not match the differing chalk and fossil assemblages exposed in Charente.
- What evidence supported the original concept?
- He relied especially on oyster-bearing chalks and their accompanying fossils; later regional revisions changed the extent of his type beds.
- How has geology changed the concept?
- Much of the original Campanian type area is now assigned to Maastrichtian, a particularly instructive case of a name surviving altered rock attribution.

Editorial qualification
Not the Italian region Campania: the derivation is explicitly given by Coquand in the Charente regional context.
