Jianshanopodia resembled the closely related siberiid
Megadictyon. The head possessed a pair of grasping frontal appendages which bore wedge-shaped plates. The trunk was annulated, with a pair of stout legs (lobopods) on each body segment. Due to the lack of a complete specimen, the exact number of body segments and leg pairs is uncertain. If it had 12 body segments, the living animal might have grown over 20 cm. == Phylogeny ==
