Summary

[edit]
Description
English: A radial thin section of the Brachyoxylon woodworthianum holotype. "Fig. 40.-Radial section. Here is shown a feature to which attention was called above, namely, the presence of nuclei in the traumatic ray-cells. Preserved in the resinous matrix, they have retained a startlingly life-like appearance. The heavily pitted rays are seen to better advantage also and the uniseriate tracheidal pitting is in evidence."

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