  • Need help identifying this Ammonite fossil

    #1
    Hello, I am new here, and this is my first post. I just bought an Ammonite shell. It is about about an inch tall, slightly larger than an inch long, and a third of an inch in width at the opening of the shell. I got it rather cheap; the seller said it is from Morocco. Now I know it will be difficult to get it down to a genus, but as far down the taxonomic scale would be most interesting to know. Thanks!

    P.S. If more pictures (or pictures with better quality) are needed, I will try to post some more.

    If Kevin is not in France drinking beer at a wine tasteing he should be by shortly to either ID or send you on a fruitful search.

      That is probably Douvilleiceras sp. from Madagascar.

      D, why would we drink beer at a wine tasting?

      two weeks to go

        Do you know any additional information about the organism?

          If that is what it is, it is Albian, Early Cretaceous, about 110 m.y. old.

            One more question; if you had a second guess as to its identity, what would it be? Okay, one more question. What order and family do you think it is in? I am assuming Ammonitida? No clue on the family.

                From the Paleobiology Database site:

                Douvilleiceras

                and/or

                Cleoniceras

                totally mis-spelled in that last post, and as far as I know Order Ammonitida is still an order of Subclass Ammonoidea

                  Great stuff! I just wanted to be able to tell people about my fossil. Thanks!

                    I am leaning towards Cleoniceras as the identity of my fossil. Here are a couple of pictures I am using for comparison. What do you think?

                    Cleoniceras https://www.juniorgeo.co.uk/images/ammonites05.jpg

                    Douvilleiceras https://www.juniorgeo.co.uk/images/ammonites06.jpg

                    I just don't think the fossil is a ribbed as seems to be the norm for Douvilleiceras. However it would be nice if it were Douvilleiceras as I could buy this wonderful reconstruction (toy) to accompany it. http://www.mini-qt.com/catalog/item/7027864/7068529.htm

                    Do you know any good sites or books for ammonite reconstructions?

                      I wonder if you could get Sordes to build you one

                        I think you are correct, Cleoniceras is a good match.

                          So I think I may be so bold as to call it Cleoniceras cleon. I do not have access to any books on Ammonites, but from some internet searching and picture comparisons, I think it is cleon.

                            I would suggest cleon's ribbing is a bit more compact than your specimen? See below:

                              Ah good point. I'll have to see if I can find any other Cleoniceras sp. pictures.
