First occurrence of the boreal fossil wood Xenoxylon meisteri from the Jurassic of North America: Morrison Formation of central Montana, USA
International audience Six specimens of the fossil wood Xenoxylon meisteri were discovered in the Upper Jurassic Morrison Formation of central Montana and are described herein. The discovery represents the first confirmed occurrence of the species X. meisteri in North America. In addition, we review...
