No Precambrian fossils are known from Ohio, so the state's fossils record does not start until the Cambrian Period. [2] During the later part of the period, Ohio was covered in seawater and located 10 degrees south of the equator. By the end of the Cambrian the sea was shallow and the climate dry. Although marine life was diverse during the ...

The Paleo Crossing site, one of the oldest sites in Ohio, had two [5] or three [6] post holes and refuse pits that contained charcoal. From radiocarbon dating, the site was used 10,980 BP ± 75 yearsBefore Present [ 5 ] or about 9,000 B.C. [ 6 ] The post holes and an area about 150 square feet indicate that there was a structure at the site.
