Calamites?

[Sizev_McJol]

This was given to me from a third hand source. I’m only assuming it’s from Illinois—I really don’t know. I supposed it was a calamites horsetail, but I’m seeking confirmation before I catalogue it. Anyone?

Node to node. Cool !

I like the 3-D preservation, cool!

Very nice preservation.

Nice gift and a good find for the first person.

Yes, and a fine specimen it is.
