Abstract
Fluorescent microscopy was proved to be effective for structural identification of permineralized plant tissues in calcite nodules from the Upper Cretaceous of Hokkaido, Japan. A minute, scale-like projection on the bract of a fossil Taxodiaceous cone is identified as a true ovuliferous scale because it is bordered with a continuous epidermis that exhibits prominent fluorescence. The presence of the ovuliferous scale suggests that the fossil is aTaiwania archetype.
