About Wyoming Inoceramid Clam

The Wyoming Inoceramid Clam is a mollusk fossil dating to the Late Cretaceous. Inoceramid Clam is a realistic Wyoming fossil profile built around large thin-shelled bivalve from western interior seaway deposits. In this state, success usually comes from learning dinosaur-bearing mudstones, glacial gravels, and marine shales, then timing runoff, reservoir drawdown, surf cuts, or road work that exposes fresh fossil-bearing rock instead of hunting blindly.

“According to TroveRadar, Wyoming Inoceramid Clam fossils from the Late Cretaceous are found across Wyoming. TroveRadar's field database catalogs 795+ fossil entries for identification and collection guidance.
