Polyedroentactinia Kozur & Mostler, 1989

Polyedroentactinia Kozur & Mostler, 1989: 194 .

Polydroentactinia – Kozur & Mostler 1989: 194 (misspelling in the title of genus description).

TYPE SPECIES. — Polyedroentactinia cisuralica Kozur & Mostler, 1989 ( Kozur & Mostler 1989: 194, pl. 12, fig. 4-7, pl. 13, fig. 3).

AGE AND LOCATION OF TYPE MATERIAL. — Lower Permian, Cis- Urals, Russia.

TAXON CODE. — 115.

STATUS. — Valid.

DIAGNOSIS. — “Die polyeedrische Schale besteht aus einem sehr groben Balkengeflecht, das viereckige bis sechseckige, selten auch dreieckige ebene Flächen abgrenzt, die ein sehr grobes Maschengeflecht mit sehr unterschiedlich grossen Poren aufweisen. Die Zahl der nadelförmig schlanken, aber trotzdem dreikantigen Hauptstacheln beträgt 7-10. Das kräftige Spicularsystem ist zentral gelegen. Von einem Medianbalken gehen insgesamt 7-10 kräftige Spiculae aus, die in die Hauptstacheln laufen. Meist gehen von einem Ende des Medianbalkens 4, am anderen Ende 3-4 Spiculae aus.” ( Kozur & Mostler 1989: 194).

DIAGNOSIS (English translation by J. P. Caulet RadWorld database – modified by Jörg Maletz). — “Polyedral shell with a coarse meshwork of quadrangular, hexagonal, or rarely triangular, flat areas, forming a very large meshwork with irregular pores of highly variable size. 7-10 slender, needle-shaped main spines with three-bladed crosssection. Usually 4 rays at one end of the median bar and 3-4 rays at the other end.”

REMARKS

Nestell & Nestell (2010: 21, 22), consider this a monotypic genus within their new subfamily Polyedroenctaciniinae Nestell & Nestell, 2010 , which they place within the family Orosphaeridae , yet they note a 6 to 8 rayed bar-centered spicule in one of their species, which would indicate placement in the entactinarians.
