Diagnoza

The sp and oz elements with typically two to four denticles on their external processes, the denticles decrease in size in distal direction from the cusp (modified after LINDSTROM
1971).

Porównanie

The apparatus of the species does not differ from other species of the genus (DZIK 1976), and the most diagnostic is the denticulation of elements of the " platform" series .

Zasięg czasowy

Stratigraphic and geographic distribution of the species in the Baltic region was presented by LOFGREN ( 1978). In the lowerm ost part of the Mójcza Limestone ( 1.2-0, 9 m below the discontinuity) the ancestor of M. ozarkodella, that is M. hagetiana STOUGE et BAGNOLl, 1991 , may be present. This is suggested by more acute external bases in rare ne elements. Regrett ably only a single juvenile element sp was found at th is level (sample MA- 122) which makes identification not certain. Undoubted M. ozarkodella appears 0.7 m below the discontinuity and occurs up to it. Specifically undeterminable specimens of Microzarkodina appear again 2 m above the discontinuity (E. robustus Subzone) . They do not seem to be reworked .
