Nannotax - Content summary and plans

topstrip

At this stage the content includes ca. 2600 taxa and ca. 20,000 images in the main part, and ca. 4200 original descritions of taxa in the Farinacci catalog. For almost all taxa at least a short diagnosis, full citation, and geological range has been provided.

The palaeontological content originally came primarily from Bown (1998) Calcareous nannofossil biostratigraphy and subsequent papers by Bown and Lees, the extant nannoplankton content came primarily from Young et al. (2003) A guide to extant coccolithophore taxonomy and unpublished images of Young. In both cases these sources have now been very significantly supplemented by additional from the broader literature.

A list of publications we have taken images from is given below. A major priority has ben to extend coverage of taxa published since the syntheses we used as our primary source.

Contributing images: There is no facility for automatic image upload yet, but we can incorporate images very easily to the system if you send them to us. For this images can be sent as individual images or as plates of multiple sub-images; we can add scalebars if all images are the same magnification, otherwise there should be a scalebar on each image; square format images work best on the system (we will add a white box around non-square images); an excel spreadsheet should be used to provide for each image the taxon identification and any other metadata (ideally including location and stratigraphic age - using standard nannofossil zones). We are particularly interested in colour light micrographs, good quality SEMs and images from published papers.

Copyright: Images from US government publications, including DSDP & ODP reports, are in public domain. We have kindly been granted use of copyright images by Journal of Micropalaeontology (The Micropalaeontological Society), Journal of Nannoplankton Research (INA), Palaeontology (Palaeontological Association), Micropaleontology (Micropaleontology Press) and Acta Protozoologica (Jagellonian University). For any publication the original plates remain copyright of the author so you can send us scans of them for incorporation.

Wishlist: There are many developments we hope to bring to the site, including:
[NB This list was written in September 2013, green comments indicate progress since then]
