Panamintaspis snowi is an extinct species of pteraspidid heterostracan agnathan which existed during the early Middle Devonian period of Death Valley, California.

[1] Fossils are found in Late Emsian-aged marine strata of the Lost Burro Formation.

P. snowi strongly resembles Pteraspis, though while it was originally described as a member of the same family, Pteraspididae,[1] a recent phylogenetic reassessment of the order Pteraspidiformes places P. snowi within the paraphyletic family "Protopeteraspidae," as the sister taxon of the suborder Pteraspidoidei (the super-taxon that contains Pteraspididae together with Protaspididae and Gigantaspis).

[2] The generic name refers to the Panamint Range in Death Valley where the holotype and other specimens were found.
