Types: Holotype, CSC 5272, see Fritz (1972). Discussion: This species is based on a single spectacular specimen that possesses more than 42 thoracic segments, including the usual complement of 13 prothoracic segments. Such a large number of opisthothoracic segments is unknown for any other olenelloid (as defined in Lieberman 1998), and therefore represents a distinct autapomorphy of the species; how- ever, Kleptothule rasmusseni Budd 1995, a trilobed arthropod from the Lower Cambrian of Greenland, although presumably distantly related to O. robsonensis, also bears a many seg- mented thorax. In all other features of its morphology, O. robsonensis matches those char- acters typical of the genus Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Peabody Museum of Natural History.
