Cretaceous sponges from the Campanian of Misburg and Höver
Scytalia * Zittel 1878

Locality:  Teutonia, Misburg

Scytalia turbinata

Roemer 1864

The specimen shown on the left has strong roots and a deep tubiform paragaster, about 10 mm wide. The paragaster outlet on the truncated top of the sponge is surrounded by narrow, radiating furrows. The surface is covered by densely crowded pores, still recognizable by the naked eye.

The rhizoclones of the skeleton are relatively large, of a stretched habit, and with few spines. Hence, according to Schrammen (1924) the species is not Pseudoscytalia terebrata, but Scytalia turbinata.

(The shell in the middle is Spondylus sp.)

. . . Another example of Scytalia turbinata showing typical concentric growth stages.

. . . Another fine example with a slightly conical top.

The specimen shown here is a variant called Scytalia turbinata var. elongata. It is more slender in habit and has many prominent concentric bulges.

*) Reid (2004) has inaccurately equated Jerea turbinata F.A.Roemer 1864 with Spongia terebrata Phillips 1835. Schrammen (1924) has shown that Jerea turbinata (=Scytalia turbinata Schrammen 1910) has a significantly different spiculation than his newly defined genus Pseudoscytalia Schrammen 1924, with Spongia terebrata Phillips 1835 as genotype.

The author has therefore added the missing genus Pseudoscytalia to the taxonomic scheme of the Treatise (Reid, 2004).
