Summary
[edit]DescriptionBrachyoxylon woodworthianum holotype radial section Torrey 1923 Plate13 fig42.png |
English: A radial thin section of the Brachyoxylon woodworthianum holotype. "Fig. 42.- Radial section of twig . This photograph was taken at the junction of medulla and primary wood. At the right is the dark resinous mass of the pith; on its left-hand border lie two small tracheids
with spiral thickenings, then follow two tracheids with reticulate markings, and next to these the most significant element of all, - a tracheid beset with alternating, mutually flattened pits. It is a striking case of the retention of true Dadoxylon pitting." Cretaceous (Turonian), 93.9 ± 0.8 Ma - 89.8 ± 1 mya, Raritan Formation, Martha's Vineyard, Massachusetts Repository not identified. |
