Orthoceras was a marine cephalopod, this particular species was straight shelled and they thrived some 400+ million years ago in the Paleozoic era.
Here are above average quality Orthoceras fossil specimens cut into a free form plaque. The plaque measures 17 1/4″ wide x 15 1/2″ tall x 1 3/4″ thick and weighs over 19 pounds. The fossils on the front face have been chipped out of the matrix and polished to reveal very good detail and unique characteristics. It has an interesting healed fracture line that adds to it’s uniqueness. A wonderful work of art.
