Synopsis

The fossil plant described is a mould formed in a Clayband Ironstone nodule by the leaf cushions of a palæozoic arborescent Lycopod. It exhibits the unaltered three-dimensional shape of the surface of the tree-trunk. The description adds to the known facts about the leaf cushions and their diagnostic features. The specimen has been placed in a new species of the genus Sublepidophloios, Sublepidophloios ventricosus.

A new method of making casts from such fossil moulds is described which involves the use of an elastic, re-meltable plastic compound. An examination of casts made by this method indicates that the plant fragment described was fossilized with the minimum amount of compression and distortion.
