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]
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).

Prehistory of Ohio provides an overview of the activities that occurred prior to Ohio's recorded history. The ancient hunters, Paleo-Indians (13000 B.C. to 7000 B.C.), descended from humans that crossed the Bering Strait. There is evidence of Paleo-Indians in Ohio, who were hunter-gatherers that ranged widely over land to hunt large game.
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]
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 ...
Burning Tree Mastodon excavation (mid-December 1989), Burning Tree Golf Course, Heath, east-central Ohio, United States. The locality was the grounds of the Burning Tree Golf Course, southern side of Ridgley Tract Road, just west of Lake Drive, south side of Heath, southern Licking County, central Ohio, United States.
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 Devonian (/ d ə ˈ v oʊ n i. ən, d ɛ-/ də-VOH-nee-ən, deh-) [9] [10] is a geologic period and system of the Paleozoic era during the Phanerozoic eon, spanning 60.3 million years from the end of the preceding Silurian period at 419.2 million years ago (), to the beginning of the succeeding Carboniferous period at 358.9 Ma.
