Anarthraspis
Anarthraspis is an extinct genus of arthrodire placoderm fishes which lived during the Early Devonian period.[1][2] It contains two species described in 1932, Anarthraspis chamberlini and Anarthraspis montanus, both found in the Beartooth Butte Formation of Wyoming and Montana, USA, and assigned to the genus in 1934.[3]
