About Pennsylvania Honeycomb Coral

The Pennsylvania Honeycomb Coral is a coral fossil dating to the Silurian-Devonian. Honeycomb Coral is a realistic Pennsylvania fossil profile built around colonial tabulate coral with tightly packed hexagonal corallites. 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 Honeycomb Coral fossils from the Silurian-Devonian are found across Pennsylvania. TroveRadar's field database catalogs 696+ fossil entries for identification and collection guidance.

Pennsylvania state guide

Fossil collecting rules in Pennsylvania vary by land status and fossil type. Common invertebrate fossils may be collectible on some public lands, but vertebrate fossils, protected park units, tribal lands, and cultural sites require a much higher level of care and often a permit. This is especially relevant in Devonian fossils, coal-age plants, and river gravels.
