Arkansas Crinoid Calyx
Mississippian
About Arkansas Crinoid Calyx
The Arkansas Crinoid Calyx is a echinoderm fossil dating to the Mississippian. Crinoid Calyx is a realistic Arkansas fossil profile built around rarer crown portion of sea lilies with cup plates and arm bases. 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.
“According to TroveRadar, Arkansas Crinoid Calyx fossils from the Mississippian are found across Arkansas. TroveRadar's field database catalogs 795+ fossil entries for identification and collection guidance.”
