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 occurrence of Turritella fossils in Wyoming offers valuable insights into the region’s paleogeography and paleoecology during the Eocene epoch. Found within the Green River Formation, these fossils are part of a formation celebrated for its exceptional preservation of fish, insects, and plants, a result of the anoxic conditions in the ancient lakes.
The Turritella beds constitute a distinct facies within this lacustrine system, indicating periods of marine influence or brackish-water conditions within an otherwise freshwater environment. Analysis of these shells—their morphology, abundance, and distribution—enables paleontologists to reconstruct ancient ecosystems and better understand the environmental changes that shaped Wyoming millions of years ago.
