Fossil wood of Abietoxylon shakhtnaense sp. nov. (Pinaceae) from the Upper Oligocene-Lower Miocene deposits of Southeastern Sakhalin

摘要

A new species, Abietoxylon shakhtnaense (Pinaceae), was erected on the basis of fossil wood anatomical characters from the Upper Oligocene-Lower Miocene deposits of Southeastern Sakhalin. A. shakhtnaense is similar to wood of firs Abies sachalinensis, A. magnifica, and A. grandis. Fossil wood with features characterizing fir anatomical structure was found in Sakhalin for the first time.
