... that Cretaceous Ceratiaceae bearing such appendages are cysts of thecae that encysted in particular environments, where light, salinity, temperature and chemistry of water masses might have been key to their development. Our conclusion is supported by the high morphological variability of horns in modern...

... of the paraplates at mid-length of each horn. All other features of O. octopus conform with the previous description of the genus. In the Family Ceratiaceae four plates form the apical horn, whereas two plates are involved in both the postcingular and antapical horns. In O. octopus the mid-length detachment...

.... However, Muderongia is classified in the Family Ceratiaceae; prior to the publication of Fensome et al.
