Hollow plant organs can react in different ways to the forces exerted during compaction of the surrounding sediments. Large infilled lycophyte stems, lying flat in the sediments, flatten and expand in width. The width of the mould that is ultimately formed will therefore approach half the original circumference of the stem rather than being equal to its original diameter.
