Bridlington fossils

Hi.  I went to Bridlington yesterday and I went fossil hunting for an hour.  I would like two fossil identifying if possible. I found 12 other fossils, but I know what they are.  The fossils which I would like identifying are a piece of chalk which I think contains a sea sponge, and a large rock with many shells in it, but I don't know how old they are.  I think the shells come from the clay which is above the chalk (83 million years old), but I'm not sure.

 

 

Any IDs would be appriciated,

 

Thanks,

 

 

Daniel

        Hi Daniel

        Is the chalk matrix as hard as Flint?

        The second specimen is Lower Jurassic - Lower Lias matrix originally from the Robin Hoods Bay area and left behind on/in the East Yorkshire coast when the glaciers receded.

        If you go fossiling on the Holderness coast keep an eye out for this type of matrix (especially large blocks) because it occasionally contains some very nice ammonites, bivalves, gastropods with some nice multi block assemblances.
