Hi! a scale would help....

also the geologic time.... if it is small could be a Cuneolina or if it is large can be many other things....!

Hello, the specimen was sampled from upper cretaceous (Upper Cenomanian?) deposits; and their length cannot be more than 0.7mm

thank's

then possibly you are very close to one of the few species of Cuneolina which perfectly fit the lower part of the upper K! enyoj!

Yes Antonino is right. It is a fragment of Cuneolina which ranges from Valanginian to Maastrichtian.

Check my book:

BouDagher-Fadel, MK; (2008) Evolution and Geological Significance of Larger Benthic Foraminifera. Developments in Palaeontology and Stratigraphy: Vol.21. ELSEVIER

Yes, it looks like a Cuneolina fragment.

MORE PROBABLY AN ADVANCED  FORM OF CUNEOLINA - POST APTIAN

It looks like Cuneolina which is appear from Barremian through Maastrichtian 

Hi!

I join the opinion of my colleagues who have written before me. I would recommend you to take into consideration the book of BauDagher-Fadel, 2008 as well as articles of Neagu 2000 and Schlagintweit, Gawlick, 2005 relating to cuneoliniform foraminifera:

Good luck!

Some Cuneolina indeed!

Could be Cuneolina, but as Carme mentioned can also be part of a Dicyclina.

In my opinion it's a Cuneolina fragment
