Myriapora truncata ( PALLAS, 1766) – Berning p. 90, Fig. 108-110 (cum syn.)

M a t e r i a l: Common and well defined species, so only 8 specimens were studied in detail. Three additional specimens from the Reuss collection stored in the Natural History Museum Vienna under the numbers 1859.50.970 (labelled as Vaginopora polystigma ) and 1859.19.157 from sections at Podivín and Sedlec were included in our studies .

D i a g n o s i s: Autozooecial apertures cleithridiate, with a very broad sinus and clearly visible condyles. Ovicell deeply immersed, almost indistinct, with porous frontal wall. Aperture in ovicelled autozooecium larger than in regular autozooecia.

R e m a r k s: Paleoenvironmental conditions indicated by Myriapora truncata ( PALLAS, 1766) were discussed in detail by Berning (2007).
