[null,null,null,"Sommario/riassunto","Graptolites flourished from earliest Ordovician to Early Devonian, a time range of about 90 million years, and were widely distributed as marine benthic and planktonic colonial organisms around then-world. They were diverse and rapidly evolving and, as such, make excellent \"\"index fossils\"\" for relative age-dating of their enclosing basinal rocks."]
