The Late Cretaceous dinoflagellate cyst Manumiella : biostratigraphy, systematics and palaeoecological signals in Antarctica
This study of the Maastrichtian (latest Cretaceous, 71–65 Ma) species of Manumiella Bujak and Davies 1983 in the James Ross Basin, Antarctic Peninsula is focussed on the biostratigraphical and palaeoecological significance of this peridinioid dinoflagellate cyst genus, in particular with reference t...
