Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M.-Z. Won and W. J. Iams 2002 | A skeleton with a spherical shell and one pointcentered spicule. The spherical shell varying from a disorderly and three-dimensionally interwoven primitive meshwork of straight to slightly curved bars to a typical spongy tissue. The point-center of the spicule positioned from eccentrically within the central shell cavity to immediately adjacent to the innermost
shell wall; rays with or without spinules (or trace of spinules); spinules with or without connection to the shell meshwork, but where all the spinules connected to the shell wall, the rays forming a part of the shell wall; rodlike rays protruding out of the shell wall as outer spines. |
