Panamintaspis snowi is an extinct species ofpteraspididheterostracanagnathan which existed during the early MiddleDevonian period ofDeath Valley,California.[1] Fossils are found in LateEmsian-aged marine strata of theLost Burro Formation.P. snowi strongly resemblesPteraspis, though while it was originally described as a member of the same family,Pteraspididae,[1] a recent phylogenetic reassessment of theorderPteraspidiformes placesP. snowi within the paraphyletic family "Protopeteraspidae," as the sister taxon of the suborderPteraspidoidei (the super-taxon that contains Pteraspididae together withProtaspididae andGigantaspis).[2]
The generic name refers to thePanamint Range in Death Valley where the holotype and other specimens were found. The specific name honors one J. C. Snow, the man who discovered the holotype.[1]
