One of the biggest and fiercest sharks 380 million years ago : Dunkleosteus
The name is made up of two words: ‘osteon’ is a Greek word for bone, and dunkel is named after David Dunkel. A noted American paleontologist whose studies focused mostly on fish fossils and best known for his work in vertebrate paleontology at the Cleveland Museum of Natural History.
This placoderm is reputed to consume anything, or at least most things, and is extremely fast and powerful. Genus of large arthrodire fish is one of the largest placoderms to have ever lived and is said to have lived during the late Devonian era, often referred to as the ‘age of fishes’.
Dunkleosteus weighed up to 8000 lb (3600 kg) and was up to 346 inches (8.8 m) long.

Specialization
They are known for their strength and ability to move their jaws rapidly, allowing them to easily kill prey animals. Fossils of Dunkleosteus have been discovered in North America, Morocco, Poland, and Belgium, among other places.
Dunkleosteus appears to be an interesting animal, however, little is known about it due to its extinction and age (it existed 360–370 million years ago). While nothing is known about many regions of the Genus of large arthrodire fish body, substantial information has been gathered from Genus of large arthrodire fish fossils and reconstructions.
Dunkleosteus was discovered to have a two-part bony and armored exterior. It consists of two pairs of pointed bony plates which form a beak-like shape. Reconstruction also revealed that some Genus of large arthrodire fish species have pectoral fins, suggesting that fin pattern in placoderms is strongly influenced by mobility needs.
Dunkleosteus terrelli is distinguished by its shark-like appearance and a prominent front lobe on its tail. Dunkleosteus was the most powerful fish during the Late Devonian era. It is reported to have reached 346 inches (8.8 m) long and 8000 lb (3600 kg) in weight, making it one of the largest placoderms ever found.
