Lorenzo:

Have a look at this link for insights:

Perhaps the new book of Dr. M. K. BouDagher-Fadel provides some more references.

Would you look at the email address, you used for the last article?

I sent the necessary information there.

Evolution and Geological Significance of Larger Benthic Foraminifera,

Authors: Marcelle BouDagher-Fadel Marcelle BouDagher-Fadel

Dear All,

many thanks for your support, I'm quite near to the solution.

Hi Lorenzo,

I found the first paper you listed at the following link:

https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=3&cad=rja&uact=8&ved=0ahUKEwj2iPjWte_bAhXEb1AKHUMtBgYQFggxMAI&url=https%3A%2F%2Fsucra.repo.nii.ac.jp%2Findex.php%3Faction%3Dpages_view_main%26active_action%3Drepository_action_common_download%26item_id%3D14274%26item_no%3D1%26attribute_id%3D24%26file_no%3D1%26page_id%3D26%26block_id%3D52&usg=AOvVaw2cUiHe60zAndgFe0y3WB11

No luck with the second paper though. However, for references on larger benthic foraminifera I would also recommend:

Hi David,

thanks for the tips and for the paper

Maybe you know something about IODP wells in the Pacific Ocean touching the Upper Cretaceous?

Best,

Hi Lorenzo,

There are plenty of DSDP/ODP sites that penetrate the Cretaceous in the Pacific. It depends where in the Pacific you are interested in as there are quite a number of sites the locations of which can be downloaded as a Google Earth .KML file at: http://www.iodp.org/resources/maps-and-kml-tools. If you are interested in the Western/Central Pacific most record Cretaceous planktonic foraminifera although ODP legs 143 and 144 tagged a drowned carbonate platform that contained LBF (see Arnaud-Vanneau & Sliter, 1995; WIlson et al., 1998). I recommend looking at the following references as a starting point:

Hi Patrick,

nice! Many thanks for you very detailed list of references. I will go through them in order to find more on upper K forams.

Best,
