Fossils
These fossils were found in three different states. At the top, the cephlopod is from a layer of limestone in Tennessee. It is probably 300 million years old.
The other two fossils are from Kentucky. They are sections of stem from a woody plant. They are not as old as the cephlopod, but still a couple of hundred million years would not surprise me.
The second picture shows some crinoids that I found in a dry creek bed in Oklahoma. They are about the same age as the cephlopod. Crinoids are sea creatures that look like a plant. These are part of the "stem." Like many marine animals, they attached themselves to a rock and stayed there.
The last picture has a nickle in it for scale.
