Thank you for pointing this out. You are doubtless correct but the reason the information is currently missing from the site is that a comprehensive monograph on Oligocene planktic foraminifera is currently in press. As soon as this published a very large set of content from it will be incorporated into the website, as agreed with the publishers and all authors. However, in advance of this Oligocene taxa have only been included in the catalog not in the main database and even putting links to modern names is not practicable.
