One of my favorite Calamites due to how well preserved its internal anatomy is! I gave this to a friend's little brother who loves fossils. -

Giant horsetail plant Columbia County, Pennsylvania Carboniferous Lewellyn Formation -
I found this in western Washington in the renton formation 38 million years ago. I don't think this is a horsetail because I don't see super defined nodes. But if anyone knows what this could be let me know.

Found this horsetail impression after our recent heavy rains.

Found this ages ago just lying alongside the road in Illinois... I think it was Illinois... heh... structure looks similar to a calamites horsetail IMO, but the symmetrical succession of the parts is curious. Any ideas?

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?

Hi, I'm mike. I have been reading forum posts for a while now, thought I'd join to share and learn.. I became aware of the local geological features late in life, but now have more time for rock kicking. The Newcastle coastline has many , easily accessible, points of interest, volcanic dykes, faults, petrified trees, fossils and exposures. They are in the stratigraphy of the Newcastle Coal Measures, Northern Sydney Basin, late Permian 252-255 Ma. The majority of preservations are Glossopterids but also horsetails, cordaites and ferns. Maybe not as spectacular as dinosa

Here is a photo of a recent find in the Cahaba Valley. The photo was submitted to the University of Alabama and it was identified as another horsetail find. It's rather delicate and I have yet to see another one like it.

I checked out this cliff face (dangerous) and found the best Horsetail fossils at the bottom, of course, but what amazed me was evidence that they grew through many layers. I threw water on one stem and broke some slag off so you can see it. That one is about 3' tall and goes through several layers. There are several that do it. I'm thinking the mud didn't crash in and crush things it silted in and the plant just kept growing. As an exlogger I've seen trees do this. The third photo is of a small stem about 1' tall at the base with all of the layers and joints intact. I left it as there i

I was into a bunch of Horsetail Calamites today and kept finding these what look like slugs. I can't imagine slugs fossilize well but they have the little antenna and everything. My guess is Horsetail whorl leaves or whatever they're called. They are about 1/2 inch long. Input would be appreciated. Good thing they're dead or my wife would not be pleased.
