An extinct genus of large armored fish (placoderms) from the Paleozoic era, known as a 'dunkleosteus' relative.
From scientific Latin combining Greek 'dino-' (terrible) and 'ichthys' (fish). Named to describe fearsome prehistoric fish with bony armor and powerful jaws.
Dinichthys and its relatives were the apex predators of ancient seas 350 million years ago—evolution's first real monsters, and we only know them from fossilized bone plates.
