My wife found this small block with what look like some little bones on the Isle of Wight last week. The piece I've blown up looks like a little fish jaw (it's 2cm long). Would this just be a death assemblage or a coprolite?

This is a disarticulated fish by the looks of it. I don't think this is a coprolite. Where abouts on the IOW was it found?  Please add a scale to all photos - a ruler is best. It would be nice to have more photos of the nodule - someone might be more knowledgeable than me. I can see at least one small vertebra in section.

Hi Colin, it was found at Bembridge. I've added a few more photos.

Could it be plant matter

You can't scratch it with a fingernail.

Very nice Brym, the verts look like they belong in a tin of salmon. As for the rock it looks like a well indurated siltstone maybe and is obviously stratified so I don't think its a coprolite.

Hi Brym, i'm no expert but would agree that its not a coprolite and the dark pieces certainly look like bone with at least one vert visable.
Apart from the apparently sharp pointed outlines coming from the 'jaw' outline i would suggest it might be a cross section through a shark fin spine - the solid round points between the sharp ones appear to indicate that as a possibility.
Would certainly like to see this after some prep, will watch with interest :-)
