These 'charophytes' are technically the 'fructification of algae', more specifically gametangia (fertile elements) and more specifically, oogonia preserved as the dentrally spiraled protective sheath of female gametangia. They are .3-.5 mm in size. Basically they belong to fossil algae (land 'plants' living in fresh water) and have been preserved because of an original calcareous composition. Three tytpical specimens shown. The pin shaft is 0.65 mm in dia.
