Dunkleosteus is an extinct Devonian placoderm (382-358 ma). It was the great apex predator of its time and the largest of all creatures that existed during the Age of Fishes - reaching a phenomenal 10 metres in length.  

Dunkleosteus is a member of the order Arthrodira with a ‘jointed neck’ that allowed for movement between the thoracic shield and its massive armoured head. Its jaws were capable of exerting enormous pressure  and studies suggest that Dunkleosteus would have been able to open its mouth quickly enough to create a partial vacuum which would have effectively sucked  prey inside the maw.

Dunkleosteus didn’t actually have teeth but had two interlocking bony plates that self-sharpened as the jaws opened and shut. These plates would have easily crushed through the armour of even the biggest arthropods that lived during this period.

A number of head and thorax fossils of Dunkleosteus have been found around the world but, to date, no trace of the soft body parts has been uncovered. This means that much about the overall anatomy of these creatures is still speculative and largely based on associations with other placoderms.
