A fossil wood specimen of par-autochthonous origin was recovered from Paleocene sedimentary rocks of the Moose Channel Formation in the Big Fish River area of Yukon. The specimen is described as a new species, Protopiceoxylon yukonense sp. nov., belonging to the extinct family Protopinaceae. The investigation compared it to holo- and paratype specimens from the Natural History Museum Berlin.
Use Cases
