Fedomia is a genus of Ediacaran organism resembling a sponge.[1]

The organisms look like sacs, often connected and occasionally radiating from a central point, and are millimetres to centimetres in length. Their surface is often patterned with a number of concave, star-shaped, spicule-like structures with six to eight points, with a diameter of 2–5 mm; these were probably flexible rather than rigid.[1]
