Abstract

Petrified wood specimens from the Dakota Formation of Utah are here described as Agathoxylon lemonii. This new species is characterized by having distinct growth rings, araucarian tracheary pitting, resin plates or plugs in its tracheids, abundant axial parenchyma, low uniseriate rays and 1–4 small, slightly bordered pits with circular to oval included apertures per crossfield. This is the first report of petrified wood from the Dakota Formation of the western United States and the first record of Agathoxylon from North America.
