They were diverse and rapidly evolving and, as such, make excellent ""index fossils"" for relative age-dating of their enclosing basinal rocks.GraptolitesChordata, FossilElectronic books.Graptolites.Chordata, Fossil.563/.55Kozlowska-Dawidziuk Anna893769Lenz Alfred893770MiAaPQMiAaPQMiAaPQBOOK9910457661203321Ludlow and Pridoli (Upper Silurian) Graptolites from the Arctic Islands, Canada1996422UNINA
