Craniata
Craniata (sometimes Craniota) is a proposed clade of chordate animals that contains the vertebrates (subphylum Vertebrata) and Myxini (hagfish) as living representatives. Craniata includes all animals with a skull, or cranium, as the name suggests.

Astraspis desiderata. Astraspids are still poorly known but recent discoveries of partially complete specimens of Astraspis desiderata, from the Ordovician of Colorado, have considerably increased their knowledge. Their dorsal headshield is made up by large, polygonal bone units and the gill openings are situated more dorsally than in arandaspids.
