Eurystichthys is an extinct genus of marine ray-finned fish from the Late Jurassic.

Naming

It contains a single species, E. brongniarti from the Kimmeridgian of France. The genus was coined by Whitley (1950) as a replacement for Eurystethus Sauvage, 1877, a genus name preoccupied by a stinkbug described by Mayr (1864). ^{[1] [2] [3] [4]} Woodward suggested a potential relationship to the ichthyodectiform Thrissops or enigmatic fish Pachythrissops , while Sepkoski (2002) tentatively placed it in the Pachycormiformes. ^{[1] [3] [5]}
