Turkmenidae is an extinct family

. 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.
