Texas Ammonite Identification
Ammonite is a realistic Texas fossil profile built around coiled marine shell with complex sutures from warm Cretaceous seas. 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.

Fossil collecting rules in Texas 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 dinosaur tracks, shark teeth, and petrified wood.
