Homostiidae (alternatively spelled Homosteidae) is a family of flattened arthrodire placoderms from the Early to Middle Devonian. Fossils appear in various strata in Europe, Russia, Morocco, Australia, Canada and Greenland.
Homostiids have flattened and elongated skulls, "toothless" jaws and large sizes, suggesting that many were probably filter feeders, similar to the noticeably flattened whale shark.[2][3][4][5] According to Denison 1978, primitive homostiids have moderately long median dorsal plates, whereas in "advanced" homostiids, the median dorsal tends to be short and broad.[1]: 69
