'''''Zenaspis''''' is an extinct genus of osteostracan jawless fish which existed during the early Devonian period. Due to it being jawless, ''Zenaspis'' was probably a bottom feeder. ''Zenaspis'' was around 10 inches (25 cm) in length. It had a horseshoe shaped head that probably sheltered a small brain.<ref>{{Cite book |url=https://books.google.com.eg/books?id=z5GhqfcmpHAC&newbks=0&printsec=frontcover&pg=RA2-PA32&dq=Zenaspis&hl=fr&redir_esc=y#v=onepage&q=Zenaspis&f=false |title=Palaeontographical Society |date=1870 |publisher=Palaeontographical Society |language=en}}</ref><ref>{{Cite web |date=2014-08-27 |title=Zenaspis: Lower Devonian Bony Fish Of Podolia, Ukraine {{!}} Science 2.0 |url=https://www.science20.com/heidi_henderson/zenaspis_lower_devonian_bony_fish_of_podolia_ukraine-257007 |access-date=2026-02-17 |website=www.science20.com |language=en}}</ref><ref>https://www.paleocodex.com/species/102710</ref> thumb|Life reconstruction of ''Zenaspis pagei''
