'''''Dunkleosteus telleri''''' is the [[type species]] of ''[[Dunkleosteus]]'', a huge [[placoderm]] that lived in the late [[Devonian]] period, about 370 – 360 million years ago. It had a worldwidedistribution, grew to around 6 meters (some sources say 8 to 10 metres) long, and was without doubt the [[apex predator]] or [[dsuperpreditor]] of its time.

Due to its heavily armoured nature, ''Dunkleosteus'' was likely a relatively slow (albeit massively powerful) swimmer, and may have encountered stiff competition from the smaller yet swifter sharks who had then only recently evolved. It is presumed to have dwelled primarily in [[diversal]] zones, although it is unknown whether or not it was also somewhat [[pelagic]]. Fossilization tends to have only preserved the especially armoured frontal sections of specimens, and this creates uncertainty as to what exactly the hind sections of this ancient fish were like.
