The occurrence of planktonic foraminifera across the K Pg boundary has been studied since the 1930s.

Like other planktonic foraminifera, " G . bulloides " carbonate onset of northern hemisphere glaciations in the late Pliocene, 2.5 3 million years ago.

Gansserina is a genus of planktonic Foraminifera ( Kingdom Protista ), included in the globigerinid family Globotruncanidae, that has a fairly wide distribution in the Upper Cretaceous ( Maastrichtian ).
4.
TEX 86 has been used to reconstruct temperature throughout the Cenozoic era ( 65-0Ma ) and is useful when other SST proxies are diagenetically altered ( e . g . planktonic foraminifera ) or absent ( e . g . alkenones)

In 1983, Malmgren and colleagues published a paper called " Evidence for punctuated gradualism in the late Neogene Globorotalia tumida lineage of planktonic foraminifera . " This paper studied the lineage of planktonic foraminifera, specifically the evolutionary transition from " G . plesiotumida " to " G . tumida " across the Miocene / Pliocene boundary.
