Genus Globotruncanella Reiss 1957

Globotruncanella havanensis ( Voorwijk 1937) emend. Brönnimann & Brown l955

Figs. 9 : 1-6; Figs. 10 : 1-15; Figs. 12 : 17-19

1937 Gobotruncana havanensis Voorwijk , p.195, pl.1, figs. 25-26, 29

1955 Rugotruncana havanensis (Voorwijk) emend. Brönnimann & Brown , p.552, pl.22, figs. 4-6 Dimensions: D = 0,34 mm – 0,31mm; d = 0,29mm; g = 0,14mm.

Remarks: In the Voorwijk's paper (1937) this species is presented and figured in a rudimentary manner, being difficult to recognise it ( Fig. 17 : 7-9 in the present paper). Brönnimann & Brown (1955) have the merit to clear up from taxonomic point of view this taxon (p.552) using the holotype from the Collection of the Mineralogical- Geological Institute, State University Utrecht, to give a correct and clear description and figuration for it. From taxonomical and rules of the ICZN, preserving the initial name they are doing an emendation of Voorwjik species which by this, way become valid.

Occurrence: Țâța Valley, Pietrosița- Fieni area Stratigraphic distribution: Maastrichtian

Specimens: LPB.IV.12429
