Are the oldest ?fossils?, fossils?

Origins of Life, 1976
A comparative statistical study has been carried out on populations of modern algae, of Precambrian algal microfossils, of the 'organized elements' of the Orgueil carbonaceous meteorite, and of the oldest microfossil-like objects now known (spheroidal bodies from the Fig Tree and Onverwacht Groups of the Swaziland Supergroup, South Africa).
