About Tennessee Orthocone Nautiloid

The Tennessee Orthocone Nautiloid is a cephalopod fossil dating to the Ordovician-Silurian. Orthocone Nautiloid is a realistic Tennessee fossil profile built around straight shelled cephalopod preserved in limestone and dolostone. In this state, success usually comes from learning roadcuts through limestone and shale, coal spoils, and stream gravels, then timing runoff, reservoir drawdown, surf cuts, or road work that exposes fresh fossil-bearing rock instead of hunting blindly.

“According to TroveRadar, Tennessee Orthocone Nautiloid fossils from the Ordovician-Silurian are found across Tennessee. TroveRadar's field database catalogs 795+ fossil entries for identification and collection guidance.
