Abstract
This paper presents the detailed LM anatomy of a gymnospermous fossil wood from the Late Cretaceous layers of the Kharga Oasis. The pitting of the radial wall of the tracheids is of an early "araucarioid" type. In comparison to the previous fossil wood data the following anatomical characteristics may be emphasized: 1.
The ray cells are 3 - 52 cells high. 2. The great number (21, 24) of the pits in the cross fields. 3. The transverse walls of the longitudinal parenchyma cells are smooth. Based on these LM characteristic features this fossil wood is described as Agathoxylon lifiyii sp. nov.
