History

Lutetian Stage, second of the four stages (in ascending order) subdividing Eocene rocks, representing all rocks deposited worldwide during the Lutetian Age (47.8 million to 41.3 million years ago) of the Paleogene Period (66 million to 23 million years ago). The name of this stage is derived from Lutetia (the ancient Latin name for Paris), France, where rocks of this age are well-exposed.

The lower boundary of the Lutetian Stage coincides with the base of the zone of the foraminiferan (pseudopod-using unicellular organism protected by a test or shell) Hantkenina nuttalli. The Lutetian Stage overlies the Ypresian Stage and precedes the Bartonian Stage.
