Extinct genus of fishes
Avitoluvarus ("ancient louvar") is a genus of extinct louvar that lived in the Peri-Tethys Sea during the early Paleogene. The first specimens were found from the Danata Formation Lagerstätten, of the Ypresian age of Turkmenistan, where they were originally thought to be smaller or juvenile individuals of the true louvar, "Luvarus necopinatus". These specimens were later reexamined, and determined to be a separate genus comprising two species.
A third species, "A. eocaenicus" is known from the Middle Eocene of the Kumsky Horizon, in what is now the Northern Caucasus Mountains in Southwestern Russia. Indeterminate remains are also known from the Ypresian Gerpegezh locality in Russia.
The following species are known:
"Avitoluvarus" differs from modern louvars in that the former's forehead does not bulge out as much, giving the appearance of having the face appear higher.
