Multientactinia Won, 1997

Multientactinia Won, 1997b: 378 .

TYPE SPECIES. — Multientactinia inconstans Won, 1997 ( Won 1997b: 379, pl. 11, fig. 1-8).

AGE AND LOCATION OF TYPE MATERIAL. — Frasnian (Upper Devonian), Gogo Formation, Canning Basin, Western Australia.

TAXON CODE. — 104.

STATUS. — Valid.

DIAGNOSIS. — “The spherical spongy shell has twelve, fourteen, sixteen (?), eighteen, or twenty rod-like outer spines that are unevenly distributed because of the eccentric position of the spicule’s median bar. Two sets of five, six, seven (?), eight, or nine rays arise from two points on a bar that forms the axis of the internal spicule, and the bar passes through the shell wall. The median bar is long and is the central part of the axis bar be-tween the two points from which the rays arise. The distal parts of the axis bar beyond the two points of ray origin form two rays of the multi-rayed internal spicule and two of the numerous outer spines. The internal spicule is exceptionally thick, nearly as thick as the outer spines. Apophyses or traces of apophyses on each ray lie very near the inner surface of the shell.” ( Won 1997b: 378).
