The stems of modern horsetails are typically hollow or contain numerous elongated air-filled sacs. Calamites was similar in that its trunk and stems were hollow, like wooden tubes. When these trunks buckled and broke, they could fill with sediment. This is the reason pith casts of the inside of Calamites stems are so common as fossils. These plants were medium-sized trees, growing to heights of 30-50 meters. Calamites were components of the understories of coal swamps of the Carboniferous Period. Calamites can be found in 52 counties, including both of Kentucky's coal fields.
