mystery ball

This fossil was found in sandstone at the base of Whitecliff bay on the Isle of Wight. One theory is that it is a gastrolith (stomach stone) but the texture suggests bone rather than rock,

 

The ball is roughly the size of a tennis ball and very spherical.

 

The rest of our finds are on our facebook page http://goo.gl/6DkPf any help is very much appreciated

    I'm sorry to say it, Crest-Star, but that's just a chert nodule. As you say, it's certainly not smooth enough to be a gastrolith, but although it looks slightly bone-fibrous in the middle left part, at best this is likely to be some kind of sponge remains (but I don't think it is). You find quite a lot of chert like this all along the south side of the Isle.

     

    Sorry..
