Hello, I picked up two items this week which I need help to ID please.  The first was from Saltwick Bay and I think it looks to be bone?  Please could someone take a look and advise? That's the first 3 photos.

The second object was from Sandsend and I've got absolutely no idea what it is. It caught my eye as it looked so unusual. It looks like the remnant of some internal structure of something, but I've no idea what. I've taken a few photos to try to capture it's many angles.

Thanks.

First one looks like an ichthyosaur vertebral centrum, emerging from a concretion and abraded after being rolled around by the waves on the foreshore.
I identified a very similar piece on 8th August in response to a query on this site:
"It is a piece of a septarian concretion. These formed when a patch of lime concentrated around something in the sediment (often a shell) a short distance below the seafloor, during the time of deposition of, in your case, the Lower Jurassic rocks at Charmouth (in your case North Yorks coast). These concretions shrank as they hardened and small cracks formed in their interior. These filled with mineral, which in your case will be calcite (lime). You have a segment of one of these concretions which has fragmented after emerging from the cliff. Because of the way they formed, it is not unusual for a decent, uncompressed fossil to be found inside them. though it may have a "crazy paving" appearance due to the changes that occurred in the concretion as it became more indurated".  Hope this helps.

Thanks a lot for that, that's great! So, the first piece is bone (Ichthyosaur vertebral centrum) and the second is geological: a piece of a septarian concretion.

Re the bone piece, do you know whereabouts on the skeleton it would be situated? It looks like an end piece but I can't really visualise it.

I am no expert on vertebrate Palaeontology, but I think more towards the 'tail end' of the backbone,
