The Paleocene Yachinaka flora of the Minato Formation from Kuji, northeastern Honshu, Japan.

Well preserved Paleocene fossil plants have been recovered from several locations in the vicinity of Kuji,northeastern Honshu, Japan. Here we provide an overview of the Yachinaka flora--one of the most diverse and well-collected assemblages. The flora is useful in reconstructing the local vegation and climate, and is interesting biogeographically in comparison with Paleocene floras known from other parts of the Northern Hemisphere. The Yachinaka flora contains three kinds of ferns, Ginkgo, Cupressaceae (Metasequoia, and two other genera), Platanaceae (two genera), Fagopsiphyllum, Alnus, Corylites, Ulmites, Trochodendroides, Zyziphoides, Nyssidium,
Nordenskioldia , a legume, Acer, Deviacear, a pentamerous flower, Celtis aspera, bignoniaceous seeds, and several unidentified angiosperms. Most of the genera, and some of the species in this flora are also known also from North America, Greenland, Scotland, Xinjiang, and Kamchatka. These fossils support the concept of a relativley homogeneous widespread, mostly deciduous vegetation surrounding the Northern Hemisphere in the Paleocene.
