Avitoluvarus

Avitoluvarus ("Ancient Louvar") is a genus of extinct louvar that lived in the Tethys Ocean during the early Paleogene. The first specimens were found from the Danata Formation Lagerstätten, of the Thanetian 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.[1]
