@@patterdaledivecave3545 I am afraid I don't have the foggiest what they are. I thought they were lying on the floor when I first saw "them" so I ignored them. But, it now looks like you are filming up at the ceiling? What I can see is that there is sulphur mineralisation of the rock and whatever they are, they appear to be on the outer side of that (but that might not be right). The rock appears to be on the periphery of slate and limestone, a better look would be needed for context. And, of course, scale.
