Arkansas Spirifer Brachiopod
Devonian-Mississippian
About Arkansas Spirifer Brachiopod
The Arkansas Spirifer Brachiopod is a marine-invertebrate fossil dating to the Devonian-Mississippian. Spirifer Brachiopod is a realistic Arkansas fossil profile built around winged brachiopod with strongly extended hinge line. 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 Spirifer Brachiopod fossils from the Devonian-Mississippian are found across Arkansas. TroveRadar's field database catalogs 696+ fossil entries for identification and collection guidance.”

Arkansas state guide
Fossil collecting rules in Arkansas 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 Mazon-like plant beds, marine invertebrates, and river gravels.
