M a t e r i a l: One fragment of an encrusting colony, with zooecia arranged in ir- regular series. Zooecia have a characteristic quadrate shape with a prominent suboral avicularium and orifice with a wide sinus. Ovicells are hyperstomial, globular with granular frontal wall.
R e m a r k s: The single specimen exhibits all of the characteristic features of this species, except that the avicularia are a little larger than in the
type
material deposited in the Natural History Museum in
Vienna
. This species has also reported from brackish water deposits, although very rarely.
BOBIES (1957)
listed multilamellar colonies of this species under a different subspecies name (
Schizoporella tetragona
spongitiformis
). There are no differences, however in morphology of the autozooecia between these subspecies and therefore the unusual growth form is perhaps only an adaptation to particular environmental conditions.
D i s t r i b u t i o n: widely distributed taxon around Alpine-Carpathians region:
Badenian (Miocene): many localities in
Vienna
Basin, mainly in Nussdorf, Eisenstadt (
Austria
–
SCHMID 1989
) and Hlohovec, Mikulov (Czech – personal observation of ZÁGORŠEK), many localities in Carpathian Foredeep mainly in Židlochovice, Podbřežice and Kralice nad Oslavou (personal observation of ZÁGORŠEK).
Sarmatian (Miocene): Schleinbach, Kalch (

–
BOBIES 1957
), Lapusna – d`Orheiu (Bessarabian –
BOBIES 1957
).
