Grypania is an early, tube-shaped fossil from the Proterozoic eon. The organism, with a size over one centimeter and consistent form, could have been a giant bacterium, a bacterial colony, or a eukaryotic alga. [2] The oldest probable Grypania fossils date to about 2100 million years ago (redated from the previous 1870 million) [2] [3] and the youngest extended into the Ediacaran period. [4] This implies that the time range of this taxon extended for 1200 million years.
