Lingulodinium bergmannii

bergmannii (Archangelsky, 1969a, p.414-415, pl.2, figs.8,11) Quattrocchio and Sarjeant, 2003, p.142.  Holotype: Archangelsky, 1969a, pl.2, fig.11.  Originally Cleistosphaeridium, subsequently Operculodinium, thirdly Downiesphaeridium, fourthly (and now) Lingulodinium.  Taxonomic junior synonyms: Solisphaeridium filamentosum (Appendix A) and Impletosphaeridium charrieri, both according to Quattrocchio and Sarjeant (2003, p.142).  Quattrocchio and Sarjeant (2003, p.142) considered this species to be the possible taxonomic senior synonym of Operculodinium radiculatum.  Masure in Fauconnier and Masure (2004, p.197) proposed the retention of this species in Operculodinium, but was not aware of the work of Quattrocchio and Sarjeant (2003).  Age: Eocene.

Parent: Lingulodinium
