Again a famous extinct beast: the dunkleosteus !

The dunkleosteus was the first marine monster known in the interested by prehistorical life people's mind. 6 meters long, 1 ton weight, dunkleosteus was a placoderm having lived on Earth at the late devonian (383-358 millions years ago). Enjoyed a very powerful bite force: 6000 Newton (till 7400 N at the blade edge). Numerous fossils in Noth America, Ploand, Belgium and Morocco.

" Dunkleosteus is a genus of arthrodire placoderm fish that existed during the Late Devonian period, about 360–380 million years ago. Some of the species, such as D. terrelli, D. marsaisi, and D. magnificus, are among the largest arthrodire placoderms ever to have lived.


The largest species, D. terrelli, measuring up to 6 m (20 ft) long and 1 t (1.1 short tons) in weight, was a hypercarnivorous apex predator. Few other placoderms, save, perhaps, its contemporary Titanichthys, rivaled Dunkleosteus in size. "

Hi,

There never was a rigourous study about the size of Dunkleosteus and to my knowledge we don't have a full skeleton of this animal so all estimates about its size are just guess. A new study suggests a size much lower than previously thought with a mean length around 3,5 meters:

A Devonian Fish Tale: A New Method of Body Length Estimation Suggests Much Smaller Sizes for Dunkleosteus terrelli (Placodermi: Arthrodira) - 2023

But until new body parts are recovered, we can't be sure about the real size of this animal.
