I wonder what this is.

Dear an expert or a specialist of a dinosaur,

I wonder what this is. Please give me detail explanation about it.

I guess that this will be an egg of a dinosaur.

Is it true or not?

Here are enclosing five jpg-files.

Bye.

    This looks like a concretion to me, not a dinosaur egg.

        Concretions are formed in sedimantary rock where suspended minerals precipitate around an object, these minerals accumulate causing the concretions that we can find now. They are commonly mistaken for fossilised eggs because of their spherical shape

         

        here are some useful links to give you a bit more information on how concretions form

            Dear Flesung - I recognize these photographs and have written a letter to you regarding their identification.

             

            I suppose the letter has not reached you yet? I agree with aisling and Fossil Guy, from the photographs, I do not believe these to be dinosaur egges, rather they are concretions which have undergone what we cann 'onion weathering'. (http://www.tads.co.uk/files/test/page_20.htm )

             

            I have sent you some information about concretions and hope this is helpful to you.

             

            All the best,

            Fiona

                Dear Flesung,

                You are welcome, glad to have been helpful. To answer your second question, in my opinion, just about everything has an educational value, in this case, it shows us the effects of 'onion rock weathering'. As a geologist/palaeontologist, I find all aspects of natural history interesting. 

                I do not think your specimen is suitable for X-Ray scanning.

                I hope this is helpful to you,

                Best wishes,

                Fiona
