Utah Inoceramid Clam Identification

Inoceramid Clam is a realistic Utah fossil profile built around large thin-shelled bivalve from western interior seaway deposits. In this state, success usually comes from learning Morrison outcrops, Green River beds, and uplifted marine limestones, then timing runoff, reservoir drawdown, surf cuts, or road work that exposes fresh fossil-bearing rock instead of hunting blindly.
