Three-dimensional reconstruction of Placoparia cambriensis showing different gaits
(A) Locomotion modeling showing two symmetrical curves in Placoparia cambriensis, one curve with low wave numbers and its symmetrical with high wave numbers (k values) which correspond with two main gaits according to Manton's conditions.9
(B) Ventral view showing the tripods.
(C1) Legs meeting close to the trilobite body (higher k values in the upper symmetrical curve).
(C2) Legs meeting on the substrate (low k values in the lower symmetrical curve). See text for explanation.
