Abstract Structural and functional features of the dinoflagellate nucleus are examined and compared to those commonly found in Prokaryotes and in Eukaryotes. It appears that dinoflagellate protists, while showing several ancestral characters also found in Prokaryotes are above the prokaryote level in terms of their organization but below that of the other Eukaryotes. Some characters are typical of dinoflagellate nuclei alone, and no correspondence is found in either bacterial nucleoïd or typical eukaryote nuclei. This supports Loeblich's (1976) proposal that dinoflagellate evolution may have been independent of that of the Eukaryotes. This concept can now be refined using an argumentation plansensu Hennig (Hennig and Schlee, 1978) and appears to be in accordance with the Mesokaryote model introduced by Dodge (1965).
