It is a fossil something, but I am not sure what it is. I’ve stumped the few people I have shown so far. It has the familiar look of Calamites, but does not have the nodes. It was also embedded within limestone, which I do not find any plant fossils in locally. It’s certainly possible, but to date I have yet to find any. The piece of limestone sheared easily along this plane. There is a loose packed material in the valleys. It is dark to brown in color, with a root like pattern of white throughout.
