 Are they a mineralized part of the rock or a separate recently deposited organic thing like an insect casing that you can pick off with a pin?

Separate 

I love spiders 😏🤘 but I don't think that's what it is. It already had a small opening so I peeled it back and this is it

Perhaps. 

They were all semi buried and the middle of the circle is like an air bubble 

Does anyone know what these red circles on all these rocks are? I tried googling it and it just brought up some type of algae that grows on rocks in aquariums. These are all from the woods 🤔
