This is a lot of four (4) fossil crinoid stems. These are very large and substantial pieces. This is not my area of expertise, so these specimens are not identified. I acquired them as part of a trade and I have no other information on them. These would be great for study, educational use, or practicing your ID skills. Because they are not identified, I am offering them at a bargain price.
Refer to the photo. The black centimeter cube is shown for scale and is not included. You are purchasing all of the specimens shown.
