Dearden et al. (2023) describe the cranial anatomy of Eriptychius americanus, provide evidence of the presence of a symmetrical set of cartilages interpreted as the preorbital neurocranium, and report that the studied cartilages filled out the head and closely supported the dermal skeleton (in that they were closer to the cranial anatomy of osteostracans and galeaspids than cyclostomes), but were not fused into a single unit around the brain (more closely resembling the cranial anatomy of cyclostomes than osteostracans, galeaspids and jawed vertebrates in that aspect).[10]
