Saturnalbaillella Kozur & Mostler, 1989

Saturnalbaillella Kozur & Mostler, 1989: 162 .

TYPE SPECIES. — Albaillella cartalla Ormiston & Lane, 1976 ( Ormiston & Lane 1976: 171, pl. 5, figs 9-15).

AGE AND LOCATION OF TYPE MATERIAL. — Lower Carboniferous, Oklahoma, USA.

TAXON CODE. — 007.

STATUS. — Junior synonym of Albaillella (by Dumitrica & Caridroit in De Wever et al. 2001: 93).

DIAGNOSIS. — “Skelett unperforiert, meist aber in den Segmenten mit einem Ring von winzigen, aussen oft (immer?) geschlossenen Poren (nur im Durchlicht erkennbar), gedrungen-bis spitz-konisch. Segmente im mittleren und distalen Teil des Gehäuses aussen meist deutlich erkennbar. 2 stachelförmige Seitenflügel sind stets vorhanden, z.T. sind sie weit distalwärts verlagert, wobei dann apical noch ein weiterer kleiner Seitenstachel auftreten kann. Die freien Enden der dorsalen und ventralen Columella sind distal zu einem aussen oft bestachelten Ring verbunden, innen weisen sie an einer Seite freie Trabekeln auf. Die übrigen Trabekeln sind in die Schale eingebaut, aber im Durchlicht meist kräftig gegen die Schale abgesetzt.” ( Kozur & Mostler 1989: 162).

DIAGNOSIS (English translation by J. P. Caulet RadWorld database – modified by Jörg Maletz). — “Test thick set, or sharp conical, imperforate, except mostly on the segment bearing a ring which has very small pores, often (or always?) externally closed (they are visible only in transmitted light). Segments externally mostly well-marked in the median and distal parts of the test. Two spine-shaped lateral wings always present, sometimes distally displaced and with an additional smaller side spine. The free ends of the dorsal and ventral columellae are distally forming a ring with external spines, its inside bearing free trabeculae on one side. Other trabeculae incorporated in the shell, but appear to be strongly differentiated from the shell in transmitted light.”

REMARKS

Saturnalbaillella was placed in synonymy with Albaillella by De Wever et al. (2001). Despite its short lamellar shell, the type species, A. cartalla fits within the morphologic parameters of Albaillella .
