Fig. 4

Size of the particles captured by suspension-feeding radiodonts. With a mesh size of 70 µm (red dashed line), P. hastata might have fed on microplankton, including phytoplankton. The mesh size was closed to 500 µm (blue dashed line) in both Aegirocassis and Tamisiocaris, which therefore likely grazed on mesoplankton. Grey area depicts prey-size variation for a given mesh size in modern suspension feeders. Diagram on the left is modified after ref. 18. Size distribution of main plankton types (right) is derived from ref. 63
