11-039 11-039 This is a kodachrome of a permineralized leaf fragment of Delnortea. The woody midrib, clearly visible on the slide, was used by William E. Stein, Jr., Ph.D. to create the polished thin-sections yielding the first images of a bifacial cambium and conducting xylem and phloem tissue of any Permian gigantopterid; shown as Figs. 23-36 (USNM 372427). Taken by John M. Miller, Ph.D. using a Nikkormat camera and ASA 25 film in sunlight, shortly after collection of the rock sample from the Lower Permian (Leonardian) Road Canyon Formation, Permian Type Section. Later photographs were taken by Sergius H. Mamay, Ph.D., USNM and William E. Stein, Jr., Ph.D. and published in AJB 75(9): 1418, 1420. copyright: none
