About Oregon Fossil Cone

The Oregon Fossil Cone is a plant fossil dating to the Mesozoic-Cenozoic. Fossil Cone is a realistic Oregon 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, Oregon Fossil Cone fossils from the Mesozoic-Cenozoic are found across Oregon. TroveRadar's field database catalogs 795+ fossil entries for identification and collection guidance.
