| Outline of Final Research Achievements |
The Kamikitaba assemblage is the first record of mesofossil preservation from eastern Asia. Several fossil flowers and seeds are described from the Futaba Group in northeastern Japan and Tevshiin Govi in Mongolia. These mesofossils were analyzed using synchrotron-radiation X-ray microtomography (SRXTM) at the Advanced Photon Source.The fossil flowers are small, actinomorphic, bisexual, semi-inferior, and multicarpellate. The floral receptacle is cup shaped with a perigynous perianth consisting of several tepals inserted around the rim. The styles are short, becoming recurved with a ventrally decurrent stigma. The fruit type is a follicle. Seeds are ca. 10 per carpel, marginal, pendulous from the broad, oblique summit of the locule. The morphological features of these fossils indicate a possible relationship to Trochodendraceae.The recovery of these fossil suggests that the basal eudicot families in eastern Eurasia area during the Late Cretaceous.
