South Dakota Belemnite
Jurassic-Cretaceous
About South Dakota Belemnite
The South Dakota Belemnite is a cephalopod fossil dating to the Jurassic-Cretaceous. Belemnite is a realistic South Dakota fossil profile built around bullet-shaped guard from squid-like marine predators in chalk and marl. In this state, success usually comes from learning chalk beds, badlands mudstones, and river gravels, then timing runoff, reservoir drawdown, surf cuts, or road work that exposes fresh fossil-bearing rock instead of hunting blindly.
“According to TroveRadar, South Dakota Belemnite fossils from the Jurassic-Cretaceous are found across South Dakota. TroveRadar's field database catalogs 795+ fossil entries for identification and collection guidance.”
