Diminutive Devonian Antiarch Placoderm Microbrachius

Description: This is a diminutive Antiarch known as Microbrachius dicki. The Antiarchs were most likely bottom dwellers whose ventral mouth was well-positioned for feeding on benthic organisms. Note the very good preservation seen here, particularly the toothed fin and growth lines on the plates. To date no specimens have been found with a tail.
