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.

摘要初步描述了来自多摩川组(晚turonian -中三东统;日本东北部Kuji群的上白垩统)。新发现的中化石提供了极好的结构细节，包括保存完好的蕨类植物的环状芽、针叶树的叶芽、种子和可能的花粉球果，以及各种被子植物的果实和种子，包括山茱萸的果实和Nymphaeales的种子。新的中化石组合与先前发表的Kuji群大化石区系是互补的。

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).
