Ediacaran discoidal impressions and related structures from Newfoundland, Canada and the Long Mynd, Shropshire, UK: their nature and biogenicity

Abstract:

The nature of the Ediacaran macrobiota (c. 580-541 Ma) remains puzzling. These first assemblages of large, complex fossils may have included early animals; giant microbial forms; and organisms representing radically different body plans that went extinct. Discoidal impressions – some forming the base of Ediacaran fronds but most found as isolated discs – dominate the Ediacaran macrobiota. However round markings may also be formed in a variety of abiogenic ways. This study investigates the ...
