About Michigan Horn Coral

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

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