Worland roots slab
Close-up of root molds in slab of upper Worland Limestone.
purple color is produced by a mixture of iron oxide and oxidized
carbonaceous material. The large root mold near the center of the slab
(between 7 and 8 on the centimeter scale) divides downward, and
smaller root hairs branch from it (see close-up). This is a vertical section
of the slab (viewed across bedding). See the accompanying horizontal
section to look down into the root molds from above.
