Previously described structures within the Precambrian supposed plant fossil Vallenia erlingi Pedersen, 1967 from southwest Greenland were re-studied using STEM, high voltage TEM and x-ray microanalysis. It is concluded that the inner cell structure most likely is caused by twinning in the mineral phlogopite and is unrelated to the original cell structure.
