Montana Inoceramid Clam Identification
Inoceramid Clam is a realistic Montana fossil profile built around large thin-shelled bivalve from western interior seaway deposits. In this state, success usually comes from learning dinosaur-bearing mudstones, glacial gravels, and marine shales, then timing runoff, reservoir drawdown, surf cuts, or road work that exposes fresh fossil-bearing rock instead of hunting blindly.

Montana state guide
Fossil collecting rules in Montana 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 Hell Creek dinosaurs, marine ammonites, and mammal gravels.
