Isle of Wight Fossils

[dinohunter93]

Hi all, 

 

I found this concretion when I was fossil hunting in Yaverland, Isle of Wight. It appears to have a tooth and bone fragments in it. I was wondering if anyone could help identify what these fossils may have belonged to. Many thanks in advance!

Does anyone know if teeth/bone from the area is resistant to acid?  It would be great to be able to dissolve the concretion in weak acetic acid (basically vinegar) to release the bone without having to "whack" the rock with a hammer.

I may be wrong, but they look more like shells in cross section, rather than bone or tooth.  

Maybe some of the folks in the area will elaborate.

First- it is not a concretion.

It is a piece of a coquina (shell laden sandstone) that has been stream tumbled.

I do not see any bone or teeth in it.

Like Ynot said, it's a piece of sandstone full of shell fragments. Occasionally you can find fish and hybodont remains in those. So, it's possible. Here are some of our finds. A cephalic head spine and dorsal hybodont spine
