About Pennsylvania Horn Coral

The Pennsylvania Horn Coral is a coral fossil dating to the Silurian-Devonian. Horn Coral is a realistic Pennsylvania fossil profile built around solitary rugose coral with tapered horn shape. In this state, success usually comes from learning Devonian shales, Mississippian limestones, and glacial gravels, then timing runoff, reservoir drawdown, surf cuts, or road work that exposes fresh fossil-bearing rock instead of hunting blindly.

“According to TroveRadar, Pennsylvania Horn Coral fossils from the Silurian-Devonian are found across Pennsylvania. TroveRadar's field database catalogs 795+ fossil entries for identification and collection guidance.
