Fossil claw?

image.jpgI Found this in Ossett, West Yorkshire, UK and it's carboniferous in age.  Is it a giant scorpion claw? I am asking this question because it has that little drip going down it, just like a fossil crab claw.  It is a rock, a claw or a plant fossil?

    It looks like a piece of branch or root with a new growth.

            Dan,

             

            Thanks for the further photos.

            I was hoping to see some sort of surface texture, but I don't (perhaps a bit leather-like).

            So I'm sorry to say I can't make an ID.

            Tabfish might be right with root. Or you could be right with the fossil claw idea.

             

            Mike

                  I guess it is a possibility; I don't have any speciments to compare it with, so I can't rule it out.

                  If you want a more reliable opinion, you'd need to show/send it to somebody to allow them to inspect it in detail as they want - such as the folks at the Angela Marmont Centre.

                    Hi Mike

                    I found this specimen of wood a few years ago on the Holderness it looks comparable with Dans specimen although it is a lot bigger.

                    Lower Jurassic 29cm in legth by 4cm thick across it's widest point.

                      Ta Tabfish,

                      but are you sure your specimen isn't a burrow?

                      (I'm obviously trading just from the photos, so I'm probably wonrg)

                      Mike

                        Definately wood Mike.

                        At the thickest end you can see the risers going up the wood.

                        I will take an image in the daylight and post.

                        Hi Mike

                        I should have posted some images from the end of the specimen, it's like just posting an image of an ammonite showing all the whorles and asking for an id when you should post an image of the keel as well.

                        Hope you can see the risers, if I had cut and polished the specimen you would be able to see them a lot better than they are, but i thought it was best to keep this in one piece.

                            Yes I agree Mike.

                            Too many risers to be going to the end of a branch.

                                In my post of 24oct13, 'Angela Marmont Centre' is a link; click it.

                                Use the address in 'Identification by post'.

                                If in doubt, call them to check on procedures - see 'Identification by phone'

                                 

                                Alternatively, you could book a visit and take your specimens with you.

                                Then you could use some of the resources at the centre (microscopes, computer, library, etc.)

                                    Like I posted on 10nov13:

                                    In my post of 24oct13, 'Angela Marmont Centre' is a link; click it.

                                    That applies mainly to photographs of specimens. I am pretty sure you can send specimens through the post, but you might be expected to include money in some form for return postage (assuming you want it back!). To make sure, contact the AMC usiing: 020-7942-5045 (identification by phone), or 020-7942-5511 (customer services), or 020-7942-5000 (general enquiries), or 020-7942-5011 (main information desk).

                                    I wonder if your putative centipede trace fossils is a cruziana

                                    http://en.wikipedia.org/wiki/Cruziana

                                    We'll see!

                                    Please put it in a new topic.
