About me


My name is Andy. I´m a fossil collector from the north of Germany writing a blog while writing a book about my favourite fossils – ammonites,
more specifically, the liassic ammonites of the Yorkshire, UK, coast. The blog will not be the book, it is a kind of diary, capturing all the things that occur doing the making of the book,
be it finding ammonites, preparing them, photographing them, literature research, desktop publishing, publishing etc etc etc.
The blog is also a communication tool to reach out to fellow collectors, who may have found better specimen than I have in my collection and persuade them
to allow me to borrow and photograph them. I´m of course also hoping for comments helping in the research of some of the ammonites.

I should add that none of the fossils shown here are for sale.
All photographs are copyright by me, unless noted otherwise – unauthorized use is prohibited.

    Great blog!!

  2. Great blog, awesome ammonites. Can’t wait for the book, any idea when it will be ready?

    • John,
      Thanks – it´s still quite a bit of work, but I´m hoping to be finished in 2014 (no month given though…)

      All the best,

    Andy, have you ever found large gastropods from the Jet Rock or Alum Shales? I’m trying to identify some that I have found on the Yorks coast and wondered if with your experience you have seen something similar. I can send photos.

    Hi andy

    nice website, well done!
    i was at robin hood’s bay yesterday and amongst a couple of ammonite fossils i found, i also found a rock with some smooth tube like fossils embedded in the rock, would you know what kind of fossil that is?



    • Joes,

      By your description that would most probably be “Dentalium giganteum” from the figulinum subzone of the lower pliensbachian.
      I put it in quotation marks, since it not really is a scaphopod mollusc (as the genus Dentalium would imply), but a worm tube,
      see here : http://pygs.lyellcollection.org/content/53/3/253.abstract.
      If you google the name you´ll also find pictures of it.

      All the best,

  5. Congratulation to your nice blog. Have you observed some muscle attachment scars on your nicely preserved specimens? All the best René Hoffmann

    Hi Andy, how’re you? My name is Giacomo and I come from Italy.
    In the last years I came in your country twice to test some fossil’s location that I found in internet…and I fell in love with Germany!
    Unfortunately in Italy we can’t search fossils…
    My best places are Buttenheim , Drugendorf and Mistelgau!
    I tried to go to Sengenthal but it was closed and I saw that I must contact someone to enter in the quarry…I hope that someone speak in English because I just speak English bad…and I don’t speak anything in German!
    I write you because I admire collectors like you that share their experiences with other researchers!
    I hope to see you when I’ll come in the north of Germany so we can go together in some places to find these treasures!
    Have a nice day Andy!

    • Hi Giacomo,

      I don’t usually collect in Germany, so there’s more of a chance to meet me collecting in Britain rather than in Germany…
      But thanks for your nice comments anyway and hope you continue to enjoy the blog…
      All the best,

    Hallo Andreas, Ich war in Februar wieder an der Holderness coast und Ravenscar und würde Dir gerne ein paar Fotos schicken. Leider habe ich dein Mail Adresse verloren, Gruß Jeff Mitchell

    Hi ANDY, You will have seen my recent post re D gracile and had expected a comment from you. Do you agree with the comments and can you add any info. I am trying to revise the Dactylioceratidae and relate the Yorkshire material with the Somerset/Dorset specimens. Any observation very welcome. Greetings, JOHN

    • Thanks, John…I’ve not actually had time to review your post, but will do this weekend..
      All the best,

    Hi Andy.
    I was very intrigued by your rescent post on Hammatoceras from NY.
    I would like to share with you some photos of a personal sample. Please send me your EMail to send you the picture.

    Hi Andy
    I found a very large section of an ammonite on Kilnsea beach on the East Coast near Withernsea. From the section I have, I am guessing it may have had a diameter of around 400-600mm. It has a very prominent keel. Would you be willing to take a look at some images and try and identify the species? Cheers Ian

    Hi Andy,
    Great blog and incredibly useful and I wonder if you can help. I recently found an ammonite on Withernsea beach so am unable to give a site location. It looks a lot like your photos of pleuroceras solare but mine has 23 ribs and has a diameter of 97 mm Could it be a solare or have I got it hopelessly wrong? Any suggestions would be much appreciated.
    Many thanks

    Hi Andy,
    Further to my previous message, I’ve taken some photos of the ammonite, would it be OK to send them to you?

    Hi Andy, I am writing a book about ammonites and was impressed with your diagram with the biometrics. Would it be possible to use the diagram in my book and give attribution? Thank you, Alan Schaffert

    Hi Andy,
    I have a huge thank you to send to you! I recently met Dean Lomax at an event in Doncaster and I took along with me two ammonites from the East Yorkshire Coast, which had been prepped by Mark Hawkes at Stone Treasures but he was unable to identify them.
    Dean took photos of them and later emailed me with identification from you – Asteroceras sp and Agassiceras scipionanum. So I would like to thank you and would like to ask if the Agassiceras is quite a rare find, especially on the Yorkshire Coast.
    Thank you again,
    Sian Pilkington

    • You´re very welcome, Sian !
      Agassiceras scipionanum is relatively rare, simply because the bed it comes from in the lower lias is exposed nowhere else but Redcar, and only if you´re lucky and the beach is not sanded over…all other finds of Agassiceras scipionanum are from the glacial drift.
      All the best,
