Summary edit

Description
English: A tangential thin section of the Sequoioxylon montanense holotype wood. "Fig. 20.-Tangential section. This was taken through the summer wood since it is impossible to get a strictly tangential section through the spring wood because of the distortion. The uniseriate rays are evident, and a little to the left of center is seen a dark resinous plate held in a cavity which marks the position of a row of parenchyma cells."

Cretaceous (Maastrichtian), 69-68 mya, Laramie Formation, Missouri River, Culbertson, Montana
