Carboniferous Calamites

Plant fossils recently found in Hazard (Perry County) Kentucky in the Breathitt Group.  These fossils appear to be Calamites from the Pennsylvanian (Carboniferous) Period.  The leaflets protruding from the stem segment lines are called Annularia though the entire fossil plant is Calamites. See the Kentucky Paleontological Society web site for more information.

Last two pictures are of Calamites living relative Equisetum (Horsetail Reed).

Thanks to my cousin Kenny for allowing me to photograph the fossils and the last picture on this post he took in Washington state (USA).
