Abstract
Abstract. A preliminary description is provided of a new assemblage of small, three-dimensional and charcoalified mesofossils from the Tamagawa Formation (late Turonian–middle Santonian; Upper Cretaceous) of the Kuji Group in northeastern Japan. The new mesofossils yield excellent structural details and include well-preserved circinate shoots of ferns together with conifer leafy-shoots, seeds and probable pollen cones, and variety of angiosperm fruits and seeds, including fruits of Cornales and seeds of Nymphaeales. The new mesofossil assemblage is complementary to the previously published macrofossil flora from the Kuji Group.
期刊介绍：
Paleonotological Research (PR) is a quarterly, peer-reviewed international journal, which focuses on original contributions primarily in the area of paleontology but also covering a wide range of allied sciences. It has been published since 1997 as a successor to the former journal Transactions and Proceedings of the Palaeontological Society of Japan. The emphasis of contributions will include global and local perspectives, and contents can cover all ages (Precambrian to the Quaternary, including the present time).
