| Abstract |
Pulleniatina is a genus of non-spinose planktonic foraminifera that evolved in the late Miocene and survives in the modern ocean. It is biostratigraphically useful because its evolution tracks through a series of morphospecies that have different biochronological ranges, and for much of its history it has exhibited rapid reversals of its preferred direction of coiling. Six morphospecies are recognized: P. finalis, P. obliquiloculata, P. praecursor, P. praespectabilis, P. primalis, and P. spectabilis. Each of these is illustrated, described, and distinguished using Scanning Electron Micrographs (SEMs) of the type material and new light microscope and SEM images. Detailed synonymy lists are presented. The biostratigraphic ranges, geographic distributions, paleoecologies, and phylogenetic relationships of each morphospecies are reviewed. |
