| Abstract: | Some female cones of Elatides were collected from the Lower Cretaceous Bantou Formation,Yongan City,Fujian Province.The present authors have studied the gross morphology and cuticular features of them.These cones are all detached from the vegetative shoots,quite small and compact,with many cone scales.They are helically arranged along the cone axis,and their apices are spiny.The characteristics described above are consistent with the genus Elatides.According to the morphological characters of the cones,and ... |
