This is about a 6" x 6" rock with crinoid pieces that are mostly on one side and what are maybe some straight shelled cephalopods. There is this circular piece that I don't know what it is. It is somewhat translucent when wet. There are other circular pieces as well as misc. bits and pieces.
Can anyone confirm whether these are cephalopods and if the circular pieces are related?
Thank you for looking.
