The location of the state of Ohio. Paleontology in Ohio refers to paleontological research occurring within or conducted by people from the U.S. state of Ohio. Ohio is well known for having a great quantity and diversity of fossils preserved in its rocks. The state's fossil record begins early in the Paleozoic era, during the Cambrian period.
The geology of Ohio formed beginning more than one billion years ago in the Proterozoic eon of the Precambrian. The igneous and metamorphic crystalline basement rock is poorly understood except through deep boreholes and does not outcrop at the surface. The basement rock is divided between the Grenville Province and Superior Province.
For scale, note the paleontologists just right of center at the base of the cliff. The Cleveland Shale is a shale geologic formation in Ohio in the United States. The Cleveland Shale underlies much of northeast Ohio in beds of varying thickness. In northeast Ohio, the member does not appear east of the Grand River. [7]
Charles S. Prosser. The Chagrin Shale is a shale geologic formation in the eastern United States that is approximately 365 million years old. The Chagrin Shale is a gray shale that begins thin and deep underground in north-central Ohio. As it proceeds east, the formation thickens, rises to the surface, and contains greater amounts of siltstone.
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.
Fossil of the Middle-Late Ordovician giant trilobite Isotelus. Life restoration of the Carboniferous-Permian amphibian Phlegethontia. Life restoration with a conifer-like body plan of the Silurian-Late Devonian tree-like probable fungus Prototaxites. John William Dawson (1888).
Eastern North America in the Middle Devonian, showing the Michigan Basin of the Rheic Ocean. In Michigan, the Bedford Shale is found in the southeast along shores of Lake Erie and Lake St. Clair; along the shore of Lake Huron north of Saginaw Bay; along the south shore of the Straits of Mackinac; north of 44 degrees latitude along the shore of Lake Michigan; and in the far southwest corner of ...
History of paleontology in the United States. Exhuming the First American Mastodon, oil on canvas by Charles Willson Peale (1806). Paleontology in the United States can first be traced to the Native Americans, who have been familiar with fossils for thousands of years. They both told myths about them and applied them to practical purposes.
