Horn coral piece?
I think it is thank you
A piece of a horn coral

@nick-white this is indeed horn coral! If you have info on the location of this find, we can work on filling out its scientific description!
It’s from central Illinois
What if it’s a calmite root fragment? Someone else posted one that looked like this. A calamite is a Carboniferous-era swamp plant whose roots have a distinctive groove pattern.
I did not know that I’m thinking it could be
Yup
likely horn coral
I’m going with calamite, you can see a part or the root at the bottom. It has a onion-like shape that you don’t see with horn corals. it doesn’t end in a point, it has a cap on the top end, and even if its an incomplete horn coral fragment, it has a pattern of thin-thick-thin that is seen in calamite roots and not in horn corals.
@mackenzie-smith could help determine if it is a calamite plant or not.
@nick-white and @mackenzie-ross-2, @a-trilobite brings up a good point that it doesn’t resemble a typical horn coral (rugose coral). However, when I look at Calamites roots (I actually don’t know the morphogenus for the roots since technically Calamites only refers to the stems) there seems to be wide ribbing and here we see wide spacing between septa. There are some horn corals that make growth rings so it may not be a horsetail node. I would suggest getting an image of the inside of the top (which is facing the bottom of this picture). I’m leaning towards horn coral but I like the idea of a horsetail root.
