2.4" Polished Cut Slab Of Fossil Turritella Shells Eocene Age Wyoming Gastropod Shells

Location: Wyoming, United States Weight: 1.4 Ounces Dimensions: 2.4 Inches Long, 1.5 Inches Wide, 0.3 Inches Thick The item pictured is the one you will receive.  Fossil Turritella shells found in Wyoming are primarily associated with the Eocene Green River Formation, specifically the "Turritella beds" within its Wilkins Peak Member.  These gastropod shells, belonging to the genus Turritella, are characterized by their high-spired, conical shape and numerous whorls. The abundance of these shells in certain layers indicates ancient shallow marine or brackish water environments that supported large populations of these filter-feeding snails The presence of Turritella fossils in Wyoming provides significant insights into the paleogeography and paleoecology of the region during the Eocene epoch. The Green River Formation itself is renowned for its exceptional preservation of fossils, including fish, insects, and plants, due to the anoxic conditions of the ancient lakes that formed there.
