A lineage phylogeny for the Paleogene planktonic foraminifera
A stratophenetic lineage phylogeny ("phylogram") is proposed for the Paleogene planktonic foraminifera, based on an extensive taxonomic review and fundamental reassessment of their geohistoric record. In this phylogeny, an attempt is made to delineate lines of genetic descent through linea...

A stratophenetic lineage phylogeny ("phylogram") is proposed for the Paleogene planktonic foraminifera, based on an extensive taxonomic review and fundamental reassessment of their geohistoric record.

The phylogenetics of 20 subgroups of the Paleogene planktonic foraminifera are summarized in a series of "plexigrams," which are graphical representations of previous taxonomic opinions.
