6.85" Polished 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 Turritell, 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, though one side has been polished to display the limestone's detailed interior fossils. It comes with an acrylic display stand.
