Platysomus (from Template:Langx Template:Transliteration, 'broad' and Template:Langx Template:Transliteration 'body')[1] is an extinct genus of ray-finned fish that lived in the Carboniferous and Permian periods. Fossils have been found worldwide.

Platysomus was about Template:Convert long, and shaped similarly to the discus fish, having the same flattened body and elongated dorsal and anal fins. Its jaws were placed vertically under the braincase, giving it a wide gape. Platysomus is thought to have fed on plankton, and lived in both fresh and salt water.[2]
