Arkansas Crinoid Stem Identification
Crinoid Stem is a realistic Arkansas fossil profile built around disk-like stem segments from sea lilies in shallow marine limestone. In this state, success usually comes from learning Mississippian limestones, chert gravels, and shale roadcuts, then timing runoff, reservoir drawdown, surf cuts, or road work that exposes fresh fossil-bearing rock instead of hunting blindly.
