The Priabonian is, in the ICS's geologic timescale, the latest age or the upper stage of the Eocene Epoch or Series.
[5] Priabona, an extinct dipteran of Pipunculidae family, is named after Priabonian, the age of deposits from which this insect is known.
[6] The Priabonian Stage was introduced in scientific literature by Ernest Munier-Chalmas and Albert de Lapparent in 1893.
The stage is named after the small hamlet of Priabona in the community of Monte di Malo, in the Veneto region of northern Italy.
Other regional stages which are more or less coeval with the Priabonian include the Jacksonian of the southeastern US and Runangan of New Zealand.
