3.4" Fossil Freshwater Snails (Elimia) In Limestone - Wyoming

This is an interesting piece of an agatized gastropod (snail) deposit (Turritella Agate) from the Bridger Formation of Wyoming. These fossils are Eocene in age or approximately 45-50 million years old. While they are commonly referred to as Turritella, these ones are technically of the species Elimia tenera. Elimia is a genus of freshwater snail while Turritella lived in salt water.

Most of the rock has been left in its natural state and the snail fossils have been exposed around the entire specimen. It comes with an acrylic display stand.
