Abstract

<p>In this study, we developed a method of classifying pollen and spore fossils based on the size, shape, and arrangement of their pores and furrows; with the aim of developing teaching materials for the classification of these fossils obtained from Ametaki lacustrine deposits. Using the proposed method, the correct-answer rate of the classification by university students was better than 62%. The results of this study showed the effectiveness of using size, shape, and arrangement of their pores and furrows as the basis for classifying pollen and spore fossils; whereas it was often difficult to identify these characteristics using a glycerol-encapsulated sample, because the observation direction was fixed.</p>
