description Robergia Overview
Robergia is an extinct genus of Ordovician trilobites in the family Remopleurididae, within the order Asaphida. It is recorded from Baltoscandian and North American strata, and its taxonomic concept has been revised as some formerly assigned species were separated into other genera. Re-examination of the type species shows a narrow anterior cranidial border, a feature used to distinguish Robergia from related remopleuridids.
