Short summary

Pulleniatina is a genus of planktonic foraminifera used in biostratigraphy. Here, we illustrate typical specimens of Pulleniatina and the likely ancestor Neogloboquadrina acostaensis from International Ocean Discovery Program Site U1488. We present a novel integration of high-definition light microscopy images, X-ray microcomputed tomography data, and scanning electron microscope images to compare the six Pulleniatina species, supporting an evolutionary model with two diverging lineages.
