Paraliliaspis egregia Novitskaya, 1994

Paraliliaspis was, at various times, placed in the families Cyathaspididae, and Anglaspididae. Currently, it is placed in Ariaspidae with Ariaspis, and Listraspis, and is considered to be closely related to the similar-looking Liliaspis, which is also from Early Devonian Ural marine strata. Anglaspis is considered the ancestor or sister-taxon of both Liliaspis and P. egregia.
