Late Ediacaran occurrences of the organic-walled microfossils <i>Granomarginata</i> and flask-shaped <i>Lagoenaforma collaris</i> gen. et sp. nov.

Abstract New occurrences of flask-shaped and envelope-bearing microfossils, including the predominantly Cambrian taxon Granomarginata , are reported from new localities, as well earlier in time (Ediacaran) than previously known. The stratigraphic range extends into System, where it had a cosmopolitan distribution. This newly Ediacaran record includes areas Norway (Baltica), Newfoundland (Avalonia) Namibia (adjacent to Kalahari Craton), puts oldest global occurrence Indreelva Member (&lt; 563 Ma) Stáhpogieddi Formation on Digermulen Peninsula, Arctic Norway. Although is rare within assemblage, these together with India Poland, suggest potentially widespread palaeogeographic distribution through middle–late interval. A microfossil Lagoenaforma collaris gen. et sp. nov. also horizons containing Dabis Namibia, fossils found Gibbett Hill Newfoundland. – association, addition low-diversity organic-walled occurs strata postdating Shuram carbon isotope excursion, may eventually be use terminal biostratigraphy. These older add growing body fossil taxa spanning Ediacaran–Cambrian boundary.
