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 696+ fossil entries for identification and collection guidance.”

Idaho state guide
Fossil collecting rules in Idaho 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 Miocene lake beds and river gravels.

Arizona Petrified Wood
Various
Petrified Wood is a realistic Arizona fossil profile built around silicified wood preserving grain, bark, or growth-ring patterns. In this state, success usually comes from learning badlands mudstones, petrified wood flats, and playa margins, then timing runoff, reservoir drawdown, surf cuts, or road work that exposes fresh fossil-bearing rock instead of hunting blindly.

Nevada Petrified Wood
