Summary

edit
Description
English: A radial thin section of the Brachyoxylon woodworthianum holotype. "Fig. 43. -That the type of pitting just shown is not the normal type of the twig tracheids is proved by this figure taken at some distance from the center, for here there is no evidence of crowding, but instead the scattering of pits commonly held to be characteristic of the Abieteae. The ray-pits are also clearly visible on the low ray, but their spindle-like form is due to the partial decay which has also produced striae and cracks in the walls of the tracheids."

Cretaceous (Turonian), 93.9 ± 0.8 Ma - 89.8 ± 1 mya, Raritan Formation, Martha's Vineyard, Massachusetts
