Dunkleosteus terrelli

A digitally colored version of the original, which can be viewed here:

Dunkleosteus terrelli (Lehman, 1956)
Placodermi (paraphyletic)

Late Devonian
Northern Hemisphere

Length: 10 m

Armed with sharpened bone instead of actual teeth, this giant armor plated fish was the largest apex predator of her time. Her kind (Placoderms) were also the first animals to reproduce through internal fertilization (sex).
