Wanneria is an extinct genus from a well-known class of fossil marine arthropods, the trilobites. It lived during the later part of the Botomian stage, which lasted from approximately 524 to 518.5 million years ago. This faunal stage was part of the Cambrian Period.Wanneria walcottana is the only known species in this genus (i.e. the genus is monotypic).
Wanneria walcottana is close to the common ancestor of the Holmiidae, and of the clade comprising Fritzolenellus, Mummaspis, Laudonia, the Biceratopsinae and the Bristoliinae. So far, cladistic analysis could not determine which two of these groups are closer. This large group together is the sister group to .
Wanneria walcottana occurs in the middle Upper Olenellus-zone of Pennsylvania (Kinzers Formation, road metal quarry and walls of demolished tenant house on Noah L. Getz farm, on Harrisburg Pike, 1 mile (1.6 km) north of Rohrerstown, about 2.5 miles (4 km) west of Lancaster, Lancaster County, 40°0′N 76°42′W / 40.000°N 76.700°W), of Nevada (Harkless Formation, North-East of Goldpoint, Dyeran, Esmeralda County, 37°24′N 117°24′W / 37.400°N 117.400°W), Mexico (Buelna Formation, Cerro Rajon, Caborca Region, 30°24′N 111°54′W / 30.400°N 111.900°W) and of Greenland.
