| Abstract: | The tree fern Psaronii is an interesting group of Palaeozoic plants,mainly growing under the tropical and humid conditions. The findings of petrified trunks of Psaronius in eastern China not only provide new data in the field of palaeobotany,but also affords some respects in the palaeoecological analysis.In the present paper two new species of Psaronius are described I with a discussion on the classification,environments of fossilization,and palaeoecological significance of the petrified materials. |
