Another ID Request

[BLT]

Can anyone tell me what this is? I found it in a creek in middle Tennessee. (Mississippian, St. Louis Limestone & Warsaw Limestone)

[ynot]

Internal cast of a brachiopod shell.

Internal casts are called steinkerns.

No problems, glad to help.

You are finding a lot of neat rocks.

I think it might be an internal cast of the Silurian brach,

Kirkidium sp

Very cool find.
