Surv. No. 294-d. 129/1 The present study discriminates between fossil algae and stromatolites. 1969Dunbar & Waage Hist. Geol. (ed. 3) viii. 182/2 Since these deposits preserve only the gross form of the colony, the algae cannot be identified biologically and the deposits are simply called stromatolites. 1979D.
