My 10 year old son found a stone whilst looking for fossils & 'crystals' he discovered a strange looking stone. Someone suggested to him that it is a fossil! If it is could someone advise us what it is please?
First, well done to your son for noticing and being curious about this object.
Second, it is not a fossil; it is a mineral - botryoidal chalcedony, which is a form of quartz.
It is forming part of a flint, which is itself a form of quartz.
I think it is a rather nice specimen.
