  MICRODICTYON Articles Microdictyon is an extinct "armored
Microdictyon is an extinct "armored worm" coated with dot-like scleritic scales, known from the Early Cambrian Maotianshan shale of Yunnan China.
Microdictyon is sometimes included in a somewhat ill-defined Phylum Lobopodia – that includes several other odd worm-like and segmented free-swimming animals that do not appear to be arthropods or worms.
The name Microdictyon is also used for a genus of green algae.

 Constancea 83.13: Cladophora hawaiiana
Microdictyon is primarily distinguished from Cladophora by its planar thallus with secondary anastomoses, but both features are also found in Cladophora to some degree, although apparently not in combination.
1994) and, indeed, Microdictyon was shown to be closely related to Cladophora section Boodleoides, leading to the hypothesis (earlier proposed by Hoek 1982, 1984) that Microdictyon evolved by the flattening of an ancestor with a morphology similar to Cladophora liebetruthii Grunow (i.e., with secondary anastomoses and branching in three dimensions).
At present the distinction between Microdictyon and Cladophora appears to be one of degree; if the thallus is planar with regular secondary anastomoses then the plant is a Microdictyon; if the thallus is planar without anastomoses, or spongiose with anastomoses, it is a Cladophora.

 Microdictyon sinicum Chengjiang
While there are some 10 species found in the Cambrian of North and Central America, Europe, Asia, and Australia, only M. sinicum is found in the Chengjiang, and it is the only one based upon more than just sclerites.
Microdictyon probably used its clawed feet to attach itself to other creatures, particularly the medusoid Eldonia.
The discovery of the Chengjiang Biota by Hou Xian-guang in 1984 resulted in a clear window on what is known as the Cambrian Explosion.

 Discovery.com - Life on the Reef: Today from the Bahamas - Dispatch 12
The Andros reef is classified by the United Nation’s World Resources Institute as facing "medium" threat from human activities.
But in places, the reef seems to be suffocating beneath the blue-green alga Lyngbya, the red macro-alga Spiridia filmentosa, and the abundant Microdictyon marinum.
Most of the scientists in this month-long survey — from mollusk specialists to plant experts to fish afficianodos — have not found their creatures in the numbers they expected here.
