Taxonomy
Pteraspidomorphi was named by Goodrich (1909).
It was reranked as the subclass Pteraspidomorphi by Bryant (1932) and Dineley and Metcalf (1999); it was reranked as the superclass Pteraspidomorphi by Van Der Laan (2019).
It was assigned to Ostracodermi by Bryant (1932); to Agnatha by Dineley and Metcalf (1999); to Chordata by Sepkoski (2002); to Vertebrata by Young (1997), Kiessling (2004) and Young (2009); and to Craniata by Long (2011) and Van Der Laan (2019).
