GRAPTOLITES
These are now all extinct, ranging from the Cambrian to the Carboniferous Periods. They were marine colonial animals possibly related to the ancestors of vertebrates (backboned animals). The saw-shaped branches
(stipes) which housed the creatures are normally found as
fossils crushed flat in shales and slates.
