Ohio Orthocone Nautiloid Identification
Orthocone Nautiloid is a realistic Ohio fossil profile built around straight shelled cephalopod preserved in limestone and dolostone. In this state, success usually comes from learning Silurian and Devonian limestones, shale cuts, and glacial gravels, then timing runoff, reservoir drawdown, surf cuts, or road work that exposes fresh fossil-bearing rock instead of hunting blindly.

Fossil collecting rules in Ohio vary by land status and fossil type. Common invertebrate fossils may be collectible on some public lands, but vertebrate fossils, protected park units, tribal lands, and cultural sites require a much higher level of care and often a permit. This is especially relevant in Devonian marine fossils, Flint Ridge, and glacial gravels.
