Pennsylvania Isotelus Trilobite Location Guide

Isotelus Trilobite is a realistic Pennsylvania fossil profile built around large trilobite often found as enrolled sections in limestone and weathered talus. 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.
