Indiana Orthocone Nautiloid Identification
Orthocone Nautiloid is a realistic Indiana 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.
