==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).

Xanthidium from Ehrenberg1837b.jpg
Scanning electron microscope image of the Cenozoic chorate dinoflagellate cyst Spiniferella cornuta, a gonyaulacacean with a 1P archeopyle, parasutural crests, gonal processes with trifurcate endings, and a distinctive apical horn. Image provided by Sarah Damassa. Species illustrated by Ehrenberg, 1837b as Xanthidium. Upper and lower left: "Xanthidium ramosum" (now Spiniferites ramosus); upper right: "Xanthidium tubiferum" (now Hystrichosphaeridium tubiferum); lower right: "Xanthidium bulbosum" (now Hystrichokolpoma bulbosum).

Update: Planned power outage

29/10/2020: Today there will be a planned power outage in the building where dinoflaj3 is hosted, starting at approximately 6 pm Atlantic Standard Time. While it is possible it will be brief enough that the UPS will carry the system through the outage, it is also possible that it may last longer than expected. Furthermore, network services to the building will be down for a period of time due to the power outages. As a result, dinoflaj3 may be down until the following day (Oct. 30, 2020).

30/10/2020: It did go down due to the power interruption (circuit breaker was tripped and had to be reset). Back up now.

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 linked 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. The Lentin and Williams Index edition equivalent to DINOFLAJ3 can be downloaded as a PDF document from the AASP-TPS website.

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.

This new version of DINOFLAJ is released in conjunction with (and slightly later than) a new version of the Lentin and Williams Index (Williams et al., 2017). One difference in content between DINOFLAJ3 and the latest Index is that "nomenclatural novelties" are proposed in the latter and are treated as already accomplished in the former. We recommend that formal reference to the Index is preferable to reference to DINOFLAJ3 (i.e. Williams et al., 2017), but should reference to the DINOFLAJ3 database be required, we recommend the following:
