Tubulipora cumulus (SINZOW 1892) Fig. 2 /1-2

1974 Tubulipora cumulus (SINZOW) – GHIURCA & STANCU p. 305, Pl. 1, Fig. 7

M a t e r i a l: Six almost complete, delicate, erect colonies with zooecial tubes arranged in irregular fascicles composed of 2 to 3 circular zooecial apertures. Zooecial walls are sparsely pseudoporous and smooth. No gonozooecia observed.

R e m a r k s: The studied specimens are almost identical with the description and illustration published by GHIURCA & STANCU (1974). Although there was no opportunity to study the original material of Tubulipora cumulus (SINZOW, 1892) , because this is the typical brackish water species in Eastern Europe and Asia, we believe that its occurrence in Danube basin is possible.

D i s t r i b u t i o n: Sarmatian (Miocene): Petricani, Visterniceni ( Moldavia), Buciumi, Copacel, Valea Morilor ( Romania) and Lapusna – d`Orheiu (Bessarabian), GHIURCA & STANCU (1974).

Figures

Fig. 2: Bryozoa: (1-2) Tubulipora cumulus (Sinzow 1892). Note marked concentric grown lines, apertures arranged in fascicles and porous frontal walls. (3) Hippadenella regularis (Reuss 1874). General view showing wide apertures with characteristic key-shaped suboral avicularium (visible on lower rows of zooecia). (4) Hippopleurifera cf. semicristata (REUSS 1848), fragment of colony with characteristically developed apertures and large pores on frontal wall. (5) Celleporina sp. general view showing small suboral avicularia, lateral areolar pores and ovicells with semicircular windows. (6) Schizoporella tetragona (REUSS 1848). Detail of few zooecia with visible characteristic aperture with wide sinus and large oral avicularia with prominent pivotal bar. All pictures were made in Paleontological Institute of Vienna University in SEM Jeol type JSM-6400 by Dr. K. Zágoršek. Scale bar 100 µm.
