Upper and lower left: "Xanthidium ramosum" (now Spiniferites ramosus); upper right: "Xanthidium tubiferum" (now Hystrichosphaeridium tubiferum); lower right: "Xanthidium bulbosum" (now Hystrichokolpoma bulbosum).

Update: Dinoflaj3!

01/2017: Taxonomic content is now updated. These introductory pages are in the process of being revised, now mostly completed.

Jan. 5: Final (?) Index and References version loaded. Introductory pages mostly assembled, now correcting errors.

WHAT IS DINOFLAJ3?

DINOFLAJ3 is a database system containing:

1. An index of fossil dinoflagellates at generic, specific and infraspecific ranks. This information in DINOFLAJ3 is based on the latest edition of the Lentin and Williams Index (Williams et al., 2017). For a detailed description of the nomenclatural approach and format of DINOFLAJ3, refer to the Introduction.
2. The classification of fossil and living dinoflagellates down to generic rank, where it is continuous where possible with the Index information. The classification is based on Fensome et al. (1993b), but has not been updated for the present version.
3. Other information and illustrations on fossil dinoflagellates as appropriate and available, including full reference information updated from the above sources and a glossary of terms.

Information is hyperlinked for convenient browsing.

DINOFLAJ3 supersedes DINOFLAJ2 (Fensome et al., 2008), which in turn superseded DINOFLAJ v.1 (Fensome et al., 1998d; Geological Survey of Canada Open File 3653). Information will be updated periodically in the form of new formal versions of DINOFLAJ. In order to avoid confusion, it is recommended that the version always be indicated when citing DINOFLAJ. Past versions will be archived and kept available.

For nomenclatural purposes, a complete electronic document is provided with fixed pagination and content. Either the document or website should be cited as:

WHAT ARE DINOFLAGELLATES?

Dinoflagellates are single-celled organisms that have two distinctive flagella during at least part of their life cycle and/or a special type of nucleus called a dinokaryon (Fensome et al., 1993b). They are probably best known as a principal cause of "red tides" and paralytic shellfish poisoning. Some groups produce resistant organic-walled, calcareous or (rarely) siliceous cysts that are preserved in Mesozoic and Cenozoic sediments and sedimentary rocks. These fossils are useful in helping to determine ages of rocks (e.g. in understanding petroleum systems) and in understanding past environments (e.g. global change studies). For more information, see the Introduction.
