Morania
Morania is a genus of cyanobacterium preserved as carbonaceous films in the Middle Cambrian Burgess Shale. it is present throughout the shale; 2580 specimens of "Morania" are known from the Greater Phyllopod bed, where they comprise 4.90% of the community. It is filamentous, forms sheets, and resembles the modern cyanobacterium "Nostoc". It would have had a role in binding the sediment, and would have been a food source for such organisms as "Odontogriphus" and "Wiwaxia".
