A diverse assemblage of marine palynomorphs was recovered from the Oligocene - Miocene section of CRP-2/2A. Most of the assemblage is composed of previously unrecognised species. Three distinct groups of marine palynomorph were recognised: (1) prasinophytes, mainly Cymatiosphaera, (2) acritarchs, ma...

A diverse assemblage of marine palynomorphs was recovered from the Oligocene - Miocene section of CRP-2/2A. Most of the assemblage is composed of previously unrecognised species. Three distinct groups of marine palynomorph were recognised: (1) prasinophytes, mainly Cymatiosphaera, (2) acritarchs, mainly Leiosphaeridia and Sigmopollis although Leiofusa is an important component of the bottom half of the hole, and (3) dinoflagellate cysts. About 27 species of in situ dinoflagellate cysts were recorded, of which seven apparently undescribed species of Lejeunecysta form a prominent component. Reworked specimens of several species of the Paleogene Transantarctic Flora occur in CRP-2/2A sediments. Several abundance peaks of reworked taxa from the Transantarctic Flora are recorded.
