Graptolites. These are "indicator fossils", identifying a time period and pointing to the almost-microscopic hard mouthparts of conodonts which give the boundary between the Cambrian and Ordovician. Graptolites are colonies, like coral. They are phosphate-based and so the limestone matrix can be dissolved away.
