Discoserra

Discoserra is an extinct genus of ray-finned fish from the Mississippian of the Bear Gulch Limestone in Montana. It is a member of the Guildayichthyiformes with a round body and a skull possessing primitive and modern traits. Discoserra is about 60 mm long. In 2006, Discoserra was hypothesized to be a stem neopterygian, although it has alternatively been placed in Cladistia along with other Guildayichthyiformes.
