It works for me because it drives me to write a post every couple of weeks, and that requires research into the ammonites I want to write about, photographs of the ammonites and maybe even a re-prep to make them presentable (allthough that sometime pushes back the publication date, because when you see those fossils through the lense, it´s so much easier to notice all the imperfections in the prep-work…).
some of their beautiful fossils. Thanks to all of you and I´d hopefully meet you next year to photograph some more !
there are just a bit more than 60 comments (and some are from me as well…)
And remember : If you comment, you have to leave a valid e-mail address, but nobody else other than me can read it and I do not pass on e-mail adresses !
And a few little steps can make it so much easier to follow this blog, as you get an e-mail whenever I write something new.
on the german Steinkern forum (www.steinkern.de/forum) as AndyS (for both forums : You still need an account there to post messages).

If you read the title of this blog and start to worry that I might stop working on the book and on the blog – well, don’t. This is just referring to the subject of this post, the ammonite genus Ovaticeras…
The title specimen by the way (you might have guessed by the quality of the prepwork) is a specimen purchased from Mike Marshall. Maximum size of the Ovaticeras on this piece is 8 cm.
where there’s an outcrop of the aforementioned bed.
which differentiates it from large Eleganticeras body chambers.
The ribs are those of a typical Harpoceratid, of weak falcoid form, receding to mere sinuous growth stripes on adult specimens’ body chambers.
It does have a simple keel with smooth areas to the side of it that also grows weaker on large body chambers.
extracted from the nodule using hammer and small chisels alone (on the kitchen table of our holiday flat, if you need to know…)
It is not my prettiest specimen, but my largest and the first of the species I’ve found.
Must be getting close to Christmas, I see Christmas trees everywhere…

This legend was immortalized by Alpheus Hyatt in 1876 by naming the ammonite genus I´d like to present to you next after her: Hildoceras.
you´ll find on places like ebay is usually quite good, although these are mostly Dactylioceras ammonites.
the main difference is the missing spiral groove on the side of the whorl.
