or spiral. The individual animals lived in a series of tiny, cup-like structures organized along the length of the graptolite skeleton. The skeletons of radiolarians and graptolites, deposited over millions of years, formed a type of cryptocrystalline quartz called chert. It is similar to flint, but probably best known to Arkansans as novaculite or
