BIG fossils found on land slide help with identifying

Littlen thinks its a dinosaur tooth20140223_181858 (1).jpg

  • No - not a dino tooth; it is part of a belemnite.

    Have a look at the annotated anatomical diagram here, and you'll see you have a rostrum, perhaps getting as far as the start of the phragmocone (judging by the hint of it splaying out) -


    The spiral ones are ammonites.

    If you tell us the location, and maybe give us a better photo, we may be able to tell you a bit more (well, probably it will be our regular Tabfish to tell us a bit more)

        The Belemnite is certainly a great specimen and with it coming from a land slide it has not been water worn on the beach, as Mike said you have the rostrum and a very big one at that.

        I have some ammonites from your area but could do with a closer image of your's to see if we could I.D it, also it looks a good specimen that could do with prepping to turn it into something even better.

        There are many fossil shops in your area that would prep it for you at a cost but I think it would be worth it.

        Nice finds!

          • Still hard to tell what the ammonite in the top two images is Ryan but it could be a Stephanoceras sp, I find the bottom one very impressive because I can see something special prepping out of the matrix.

            Well done, very nice finds.

                I think the bottom ammonite is an Amaltheus sp, quite rare and sort after especially if it is a large one.

                I once had one from your area in my collection but I swapped it on, I have attached a couple of images of a Holderness coast one that I found and prepped.

                Generally speeking the ammonites from Yorkshire are in a lot harder matrix than some of those found on the south coast so yours should be a bit easier to prep and by the looks of your specimen most of the work to remove the matrix has been done before you found it suggesting the rest may come of the fossil without too much hard work.

                Safety glasses are a must if you are going to have a go at prepping it, a small hammer and darts! work well if you are just starting (image below)

                Try not to touch the ammonite with any tools that you use, just get as close as you can as you try to remove the matrix.

                Don't rush, large vertebrate fossils somtimes take years to prep.
