What is "turkmenidae"

Turkmenidae is an extinct family of lamprids from the Paleogene of Turkmenistan. They were small, disk-shaped fish that bore a strong resemblance to their closest living relatives, the opahs.

Turkmene and Danatinia are found in the Thanetian epoch (of the Paleocene) sections of the Danata Formation lagerstatten of Turkmenistan. Analectis is found in Late Oligocene strata elsewhere in Turkmenistan. After the extinction of Analectis, Turkmenidae disappears from the fossil record.
