Abstract
Described is a new species belonging to a new genus of petrified wood,Oguraxylon yubariense sp. nov. It exhibits characteristics of the Taxodiaceae in general anatomy and closely resemblesTaxodioxylon sequoianum andT. albertense. It is, however, unique in having tertiary spiral thickenings on the walls of the tracheids, which have never yet been found in any extent or extinct species of the family.
