Africanaspis Explained

Africanaspis is an extinct genus of groenlandaspidid placoderm known from two species, Africanaspis doryssa, named in 1997 from fossils discovered in South Africa[1] and Africanaspis edmountaini, named from fossils described from South Africa during 2017.[2] A. edmountaini is only known from juvenile specimens. Both species are known from the Witpoort Formation. A. doryssa reached long.[3]
