Went to Ruxton England looking for my own mammoth. Brought home some large rocks instead. Not sure what to make of the orange inclusion in this piece of flint. The whole flint is about 3 by 5 inches with multiple rough spotty enclusions There is significant discussion as to what these flints represent, one concept involves the death and collapse of glass sponges as in: https://www.flint-paramoudra.com/flint-nodules.html Is it a dying glass sponge, a worm and worm burrow, or something else entirely. Help will be appreciated, thanks
