See text Microdictyon is an extinct armoured worm-like panarthropod coated with net-like scleritic plates, known from the Early Cambrian Maotianshan shale of Yunnan China and other parts of the world.

Microdictyon is part of the ill-defined taxon – Lobopodia – that includes several other odd worm-like animals that resembling worm with legs, such as Hallucigenia, Onychodictyon, Cardiodictyon, Luolishania, and Paucipodia.

The isolated sclerites of Microdictyon are known from other Lower Cambrian deposits.

[1] Microdictyon sinicum (Chen, Hou and Lu, 1989) is typical.

The wormlike animal has ten pairs of sclerites (suggestions that these may be eyes or eye-like structures have no weight[2]) on the sides, matched to a pair of tentacle-like feet below.
