Kansas Devil's Toenail Oyster Identification
Devil's Toenail Oyster is a realistic Kansas fossil profile built around curved Gryphaea oyster common in marine clays and chalky beds. In this state, success usually comes from learning red beds, chalk cuts, and dry creek gravels, then timing runoff, reservoir drawdown, surf cuts, or road work that exposes fresh fossil-bearing rock instead of hunting blindly.
