The fossil pieces of " Runcaria heinzelinii " that have been found are short branched stems that at their tips have a radially symmetrical megasporangium surrounded by a cupule.
It can take one minute to create a 12 mm deep cupule on weathered sandstone, but 45, 000 and 60, 000 hammer-stone strokes on unweathered quartzite.
