Zenaspis NT Small

''Zenaspis'' is an extinct genus of jawless fish which existed during the early Devonian period. Due to it being jawless, ''Zenaspis'' was probably a bottom feeder. The fish was around 10 inches (25 cm) in length. It had a horseshoe shaped head that probably sheltered a small brain.
