    Fossil Leaf Positive-Negative
    Mazon Creek
    Grundy County, Illinois
    3.96 x 2.09 x 0.67 inches (10.05 x 5.31 x 1.70 cm)

    Rock hounds with a penchant for fossils will be familiar with the Mazon Creek locality for material from the Pennsylvanian. This specimen is the typical positive-negative fossil leaf in a rock nodule but which is far from common. The oblong, now split, rock features fossil leaves on each side which are dark brown as is the matrix but which nonetheless exhibit finer definition. Powdery white highlights add some color and contrast.

    [Scale: 1 inch, with mark at 1 cm]
