Concentric rings, radial structures, bed-parallel orientation, and disc-like shapes are common in chondrophorine and related medusa (Hyman 1940; Fryer and Stanley 2004).
The concentric rings of the King Square specimens are not usually circular or parallel to one another as in chondrophorine floats; rather, they exhibit weak semi-parallel arrangement and often have a sinuous to wavy pattern (e.g., Fig.
Scenella and "A chondrophorine (medusoid) hydrozoan from the basal Cambrian (Placentian) of Newfoundland".
