Leaf Fossils

These leaf fossils, measuring 2.5 and 2.25 inches long embedded in rock measuring 7 inches wide, 5.5 inches tall and 1.25 inches thick, originate from the Fort Union Formation near Glendive, Montana. Their distinctive orange-brown coloration contrasts sharply with the surrounding shale matrix, enhancing the visibility of fine anatomical details preserved in strong relief. Some surface touchups may be present where natural flaking occurred during extraction, preserving the integrity and scientific value of these specimens. Ideal for collectors and researchers, these fossils offer a tangible connection to ancient plant life in the region.
