Calamitaceae is an extinct family of plants related to the modern horsetails. Some members of this family attained tree-like stature during the Carboniferous Period (around 360 to 300 million years ago). The family takes its name from its principal genus Calamites.
Because some proposed species are based on partial fossil records, it is not clear if these are merely different parts of the same type.
