Fossil teeth?

Can anyone tell me if this is a fossil of a set of teeth? Found 12.8.13 on Monmouth Beach, Lyme Regis

    Hi LouLou,

     

    Congratulations! Fossil teeth and jaw. Please can you send with a scale bar, for e.g. send one photo next to a ruler.

    Lovely find, thank you for sharing - when you send the scale, we can identify this further,

    All the best,

    Fiona

    Hi there,

     

    I have been scrutinising your pictures and I think there's a good possibility that your section of jaw is from a large skull I found back on 31/03/13. I found a very large nodule on Monmouth beach which was about 80 cm long and contains around a third of the skull including the eye sockets and part of the body. I also found parts of the jaws a few days later. I have most of the skull now minus a few pieces of jaw and overall it would have originally been around one metre long.

    The jaw sections have the same cross section as your piece and the teeth are the same size and orientation.

    The ichthyosaur is a juvenile of the species Temnodontosaurus platydon. Complete it would have meaured between 2.5 - 3.5 metres. The adults grew to around 10 - 12 metres!

     

    I was wondering if it was possible to see a picture of the reverese side of the jaw to see if it looks the same a my bits?

     

    Regards,

     

    Fiann

        Hi Lou,

         

        Thank you very much for adding the extra picture. From the matrix on this side of the fossil it looks like it might be from another skull.

        Could I enquire as to whereabouts on the beach/how far along you found this piece?

        This looks like classic 'beef' limestone matrix whereas mine was found in a harder form of limestone. From the size of yours and the shape of the teeth I would say it still looks like Temnodontosaurus although without most of the skull and paddles it is hard to identify ichthyosaurs to species level. Still, a very nice find; well done.

         

        Here is a picture of my skull. I am still in the very long process of preparing it and it has already had in excess of 75 hours spent on it! So far I have removed many kilograms of matrix with air tools. The next stage is to put it in successive acid baths to remove the last bits of limestone from the bone. A delicate process but it gives incredibly detailed results if done properly. I have more of the jaw and body which are in similar stages of preparation. As you can see I have many gaps in the jaws which I need to fill by hopefully finding the rest of it! The teeth and eye socket are looking good so far though. If I can find all of the other bits of the jaws the skull should measure around 100 cm in length (and still a baby!).

        Thank you again for your reply.
