So, the idea here is that we can use the commenting tools to discuss anything about the site or coccolithophores. If discussions get long we can split the page into different topics. If no-one says anything we may quietly remove the page.However, we will read every comment posted here so feel free to use this for:
Tags, Metrics and Advanced Search - for INA16 in Athens we have launched a major upgrade to the site. All cenozoic taxa have been reviewed and data added in terms of a set of 'tags' for morphological characters and 'metrics' (coccolith and coccosphere size, liths per sphere, elements per lith). This data has been applied systematically and can be used to from the Advanced Search page (Tools Menu) to aid identification. The system is a bit complex so do read the explanatory page (About Nannotax menu).
Great! I found this site. Grateful to the Organizers.
I sometimes have difficulty identifying these Nannofossils forms on Light microscope, because some of them looks alike.
Please I also wish to know the BEST method for preparing Nannofossils Slide for enhanced recovery.
Lastly at what temperature should these slides be dried using the Electrical Hotplate.
Methods - there is a useful overview of methods in Bown (1998) Calcareous nannofossil biostratigraphy. For drying slides it is best to use a fairly low temperature (around 60°C), as you do not want to boil the water.
Best way to enhance recovery? that depends on the sample but the best technique to start with is almost always to do a direct smear (i.e. mix a little sediment in a drop of water on slide and then smear it over the slide with a toothpick). Then having seen what is in the rock you can try experimenting with how to improve recovery - but for most routine work we just use smear slides.
LM identification - they are not always easy, but as you study them you will learn more.
We are using these terms as indicators of relative taxonomic position. So for example all the species inside a genus can be described as daughter taxa of that genus and they are sisters of each other. The whole database is organised hierarchically so it is quite convenient to use these sort of terms.
Sorry if this is confusing - there is nothing really ver technical about this we are just using the terms to indicate relative position in the classification, as used on the site. So if we consider the family Rhabdospheraecae its daughter taxa are are all the genera within it -Acanthoica, Algirosphara etc. and its granddaughter taxa are all the species within it - Acanthoica acanthifera, Acanthoica acanthos etc.
