Dunkleosteus helicopters A race in decline isThe Dunkleosteus was an armoured fish with a length of eight to ten metres, which was unusually large for the Devonian period. It was one of the first giants of the underwater world, together with the Titanichthys. It was a fearless hunter who could snap incredibly fast and ate large sharks, and even its own kind if no other prey was to be found. Fossils of fish, which were only half digested, have often been discovered alongside its skeleton.
