Properca Explained

Properca is an extinct genus of prehistoric marine perciform fish that lived in Europe throughout much of the Cenozoic, from the Paleocene to the Miocene epochs.^{[1] [2]}

It is often placed with the southern perches (family Percichthyidae), which are now present only in the Southern Hemisphere; however, this is based on an outdated treatment of the taxon.^{[3] [4] [5]} Other recent studies have placed it in the Percidae.^[6]

The following species are known:

• P. angusta (Agassiz, 1836) - Middle-Late Paleocene of France, mid-Miocene of Bulgaria
• P. prisca (Agassiz, 1834) - Late Eocene of the Czech Republic (syn: Bilinia uraschista Obrhelová, 1971)

The species Properca sabbai has been reclassified into the genus Repropca in the extinct family Repropcidae.^[7] Further revision of the genus is likely necessary.
