About Idaho Fossil Cone

The Idaho Fossil Cone is a plant fossil dating to the Mesozoic-Cenozoic. Fossil Cone is a realistic Idaho fossil profile built around cone or seed structure preserved in lacustrine mudstones or silicified deposits. In this state, success usually comes from learning marine shales, volcanic ash beds, 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, Idaho Fossil Cone fossils from the Mesozoic-Cenozoic are found across Idaho. TroveRadar's field database catalogs 795+ fossil entries for identification and collection guidance.
