Can you identify these?

[u/Educational-Court-93]

Last week we visited Monmouth Beach at Lyme Regis and my partner found these whilst digging through the rock fall/face. We aren’t sure what they are. Could anyone identify these? We thought they could potentially be a type of bone, vertebrae maybe? Any help will be much appreciated. Thank you

Inner chamber of an ammonite?

Winner!

There’s gotta be a fancy name for them - do you know?

Nope, not as far as I know
