George Jennings Hinde (1839–1918) was a pioneering geologist and paleontologist. Not only did he contribute greatly to the conodont research field by making innovative studies on Ordovician and Devonian faunas (see e.g., von Bitter, 2004), he was one of the first to describe scolecodonts, the jaws of polychaete worms. Scolecodont publications prior to Hinde's (1879, 1880, 1882, 1896) four contributions were few and merely included descriptions of one or a few specimens. Hinde was aware of the taxonomic affinity of these fossils, a discovery that he ascribed to the Swedish paleontologist Nils Peter Angelin (Hinde, 1882, p. 3–4). Moreover, he was first to investigate these fossils from the world-famous island of Gotland, Sweden (Hinde, 1882), from which most studies on Silurian scolecodonts subsequently have been carried out (Eriksson et al., 2004). Although he understood that the scolecodonts were parts of complex jaw apparatuses, he felt forced to use a single-element-based taxonomy (see Hinde, 1879, p. 373–374). He described close to a hundred “species” and varieties, and many of these names are still in use. Hence, Hinde's scolecodont heritage is still very much alive and his type collections are critical for the study of these fossils, particularly for resolving nomenclatural and taxonomic problems. In this note we discuss, and illustrate for the first time, the graptolites briefly mentioned by Hinde (1879) and describe the important stratigraphic information that they contribute to his Upper Ordovician scolecodont types.
