"The Orthoceras display plate is 20 inches tall. It features One reaaly huge polished orthoceras raised from the matrix. This is one of the biggest I have seen! It has excellent detail. This is an exceptional piece!There are several smaller fossils as well.The matrix itself has several unpolished specimens visible as well. The matrix dimensions are about 20 x 12 inches. This is a stunning, yet affordable, example of 450-million year-old Moroccan sea life."
