A new assemblage of Late Cretaceous fossil plants (the Kamikitaba assemblage) was discovered from the Ashizawa Formation of Futaba Group (Early Coniacian; 89Ma). The flora includes well-preserved mesofossils of angiosperm flowers, fruits, seeds, leaf fragments and woods.
Some aspects on the origin of angiosperms and the vegetational consequences of Cretaceous and Paleogene flora are reviewed in the paper.
