Florida Devil's Toenail Oyster Identification

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