Nebraska Inoceramid Clam Identification

Inoceramid Clam is a realistic Nebraska fossil profile built around large thin-shelled bivalve from western interior seaway deposits. 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.
