Canopy flow and rangeomorph communities. A: Bedding plane, at Mistaken Point, Newfoundland, showing the preservation of rangeomorph taxa. B: Schematic of the reconstructed community showing the velocity gradient (blue arrows) and large Kelvin-Helmholtz vortices. C: Kelvin- Helmholtz vortices visualised at the boundary between parallel flows of different velocity. D: The waving of a vegetated canopy produced by Kelvin-Helmholtz vortices. E: Kelvin-Helmholtz Vortices produced in a cloud layer. Arrows in C-E indicate the relative velocity of flow. F: ‘The Fields’ by Vincdent van Gogh was among a number of his paintings inspired by Kelvin-Helholtz behavior of fields and clouds. Image credit: Current Biology
