i;o UPPER CRETACEOUS-LOWER TERTIARY FORAMINIFERA 



recorded the Maestrichtian in this well as unconformably overlain by a very thin 

 Danian section (i metre thick) which is conformably overlain successively by the 

 Paleocene and the Lower Eocene. Their Paleocene was divided into three successive 

 zones, lower, middle and upper. Apparently they considered the Danian separately 

 from the Paleocene, but described strata with a typical Upper Danian fauna as 

 lower Paleocene. This is proved by the occurrence of G. compressa (Plummer), a 

 typical Upper Danian index fossil, in what they described as Lower Paleocene (above 

 the Danian), and by the first appearance of G. angulata (White), a typical Danian- 

 Middle Paleocene boundary marker, in their so-called Middle Paleocene. Again they 

 described G. acuta Toulmin, an Upper Paleocene guide fossil, from their Lower 

 Eocene. According to the distribution of pelagic species in their section, both their 

 Danian and Lower Paleocene actually represent the Upper Danian, their middle and 

 upper Paleocene are in fact Middle Paleocene, and their Eocene is the Upper Paleo- 

 cene. 



Brotzen & Pozaryska (1961) recorded this species as ranging from the uppermost 

 part of the Danian through the Middle Paleocene (as interpreted here) being most 

 typically developed in the latter. The species was stated to be rare higher in the 

 section where it shows all the peculiar variations, while below the uppermost 

 Danian the specimens were merely considered as variations of G. daubjergensis. 



In the Esna-Idfu region G. kozlowskii appears in the uppermost Danian with 

 forms transitional to G. daubjergensis Bronnimann ; it crosses the Danian-Middle 

 Paleocene boundary and occurs as a rare form in the lower part of the G. angulata 

 Zone.
