Dunkleosteus. Dunkleosteus is an extinct genus of large arthrodire ("jointed-neck") fish that existed during the Late Devonian period, about 382–358 million years ago. It was a pelagic fish inhabiting open waters, and one of the first apex predators of any ecosystem. [ 1]
Well-represented in both freshwater and marine fossils since the Devonian, they are now represented by only two extant marine species in the genus Latimeria: the West Indian Ocean coelacanth (Latimeria chalumnae), primarily found near the Comoro Islands off the east coast of Africa, and the Indonesian coelacanth (Latimeria menadoensis).

Prehistoric fish are early fish that are known only from fossil records. They are the earliest known vertebrates, and include the first and extinct fish that lived through the Cambrian to the Quaternary. The study of prehistoric fish is called paleoichthyology. A few living forms, such as the coelacanth are also referred to as prehistoric fish ...
Dunkleosteus terrelli, a large fish found in Ohio Paleogeographic reconstruction showing the Appalachian Basin area during the Middle Devonian period. During the early Devonian only eastern Ohio was still covered by the sea. Ohio was located near the equator. Brachiopods and echinoderms still remained in the area during the Early Devonian. [3]
Leedsichthys is an extinct genus of pachycormid fish that lived in the oceans of the Middle to Late Jurassic. [ 1] It is the largest ray-finned fish, and amongst the largest fish known to have ever existed. [ 2] The first remains of Leedsichthys were identified in the nineteenth century. Especially important were the finds by the British ...
Daeschler, Shubin & Jenkins, 2006. Tiktaalik ( / tɪkˈtɑːlɪk /; Inuktitut ᑎᒃᑖᓕᒃ [tiktaːlik]) is a monospecific genus of extinct sarcopterygian (lobe-finned fish) from the Late Devonian Period, about 375 Mya (million years ago), having many features akin to those of tetrapods (four-legged animals). [ 1] Tiktaalik is estimated to ...
Researchers said they looked at ancient fish teeth from the carp family recovered from Gesher Benot Ya’aqov, a waterlogged area that once sat on the shore of the paleolithic lake Hula in the ...
The evolution of fish began about 530 million years ago during the Cambrian explosion. It was during this time that the early chordates developed the skull and the vertebral column, leading to the first craniates and vertebrates. The first fish lineages belong to the Agnatha, or jawless fish. Early examples include Haikouichthys.
