Hydrodynamic insights into the paleobiology of the Ediacaran rangeomorph Fractofusus misrai
Summary: The Ediacaran of Newfoundland preserves some of the oldest complex macroscopic communities, several of which are dominated by the fractal-like rangeomorph genus Fractofusus. Here we use computational fluid dynamics and a detailed reconstruction of Fractofusus misrai to document for the firs...
