Abstract

SynopsisSix new specimens of petrified cupules ofHydraspermacf.tenuisfrom Oxroad Bay, East Lothian (Cementstone Group) have been examined. Sections of one show a close similarity in size and shape to compressed cupules ofSphenopteris bifidaL. and H. from the Lewis Burn (Scremerston Coal Group or lower Viséan) of Northumberland. The conclusion reached is that cupules ofHydraspermacf.tenuisLong are petrified equivalents of the compressed cupules ofSphenopteris bifidaL. and H. The morphological significance of this identification is discussed.
