TYPE SPECIES. — Gedauia bibrachialis Won, 1983 ( Won 1983: 153, pl. 3, fig. 1-8, pl. 14, fig. 6, text-fig. 5n-q).
AGE AND LOCATION OF TYPE MATERIAL. — Lower Carboniferous, Rheinischen Schiefergebirge, Germany.
TAXON CODE. — 137.
STATUS. — Junior synonym of Paramphibrachium Kozur & Mostler, 1978 (by De Wever et al. 2001: 182).
DIAGNOSIS. — “Das Skelett besteht aus einer oder mehreren sphäroidalen zentralen Schalen, die von einigen konzentrischen, äquatorialen, reifenförmigen, peripheren Schalen umgeben sind. Alle Schalen bestehen aus einem Gitterwerk. Dem Rand der Reifenschalen entspringen in variabler Zahl markante Arme. Jeder Arm besteht aus zahlreichen, zusätzlichen, zueinander kongruent angelegten Reifenschalenteilen. Die Oberflächenstruktur der Arme ist im Gegensatz zum Mittelteil des Skeletts nicht schichtig, sondern eher mit der Struktur einer Siebplatte vergleichbar.” ( Won 1983: 153).
DIAGNOSIS (English translation by J. P. Caulet RadWorld database – modified by Jörg Maletz). — “Test consists of one or several spherical central shells, surrounded by a concentric, equatorial, annular, peripheral shell. All shells latticed. A variable number of arms originate from the border of the annular shell. Each arm constituted by numerous additional and anastomosed parts of the annular shell. Contrary to the median part of the test, the surface structure of the arms is not multi-layered, but it can be compared to the structure of a porous plate.”
REMARKS
Although the central part of the type species of Paramphibrachium ( Amphymenium alienum Rüst, 1892 ) does not show a spherical shell inside, it can be inferred. Rüst’s drawing ( Rüst 1892: pl. 24, fig. 2) can be compared with the image in transmitted light of Gedauia bibrachialis in Won (1983: pl. 14, figs 6a, 6b), which is considered a synonym.
