59 A Typical (?) Dinoflagellate Life Cycle

60 Adnatosphaeridium 29 30 Hystrichosphaeridium Fossil Dinoflagellates: Hystrichospheres Oldest: Triassic (200 MYA)

61 Moldowan et al. 1996. Hemostratigraphic reconstruction of biofacies: Molecular evidence linking cyst-forming dinoflagellates with pre-Triassic ancestors. Geology: 159-162. New data from numerous detailed mass-spectrometric studies have detected triaromatic dinosteroids in Precambrian (600 MYA) to Cenozoic rock samples. Triaromatic dinosteroids are organic geochemicals derived from dinosterols, compounds known in modern organisms to be the nearly exclusive widely occurring products of dinoflagellates.

62 Blooms
