Illinois Horn Coral Identification
Horn Coral is a realistic Illinois fossil profile built around solitary rugose coral with tapered horn shape. 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.
