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