Paleopleurocapsa wopfnerii gen. et sp. nov.: A Late Precambrian alga and its modern counterpart. Proceedings of the National Academy of Sciences of the United States of America 72, no. 7: 2488-2492.1091-64900027-8424http://nrs.harvard.edu/urn-3:HUL.InstRepos:3119531Silicified dolomite of the approximately one billion year old Skillogalee Dolomite of the Adelaide Geosyncline, South Australia, contains organically preserved microfossils of a structurally complex, crustose pleurocapsalean cyanophyte, herein described as <i>Paleopleurocapsa wopfnerii</i>. Although actual cell contents have been degraded, lamellar sheath material faithfully preserves the morphology of the alga. Comparison with specimens of the modern genus <i>Pleurocapsa</i> Thuret demonstrates affinities at the family level and quite possibly even generic identity.en-US2014-10-2210.1073/pnas.72.7.2488
