Redlichiida genera

Redlichia is a genus of redlichiid trilobite in the family Redlichiidae, with large to very large species (up to long). Fossils of various species are found in Lower Cambrian (Toyonian)-aged marine strata from China, Korea, Pakistan, the Himalayas, Iran, Spain, southern Siberia, and Antarctica, and from Middle Cambrian (Ordian)-aged marine strata of Australia.

Olenellus is an extinct genus of redlichiid trilobites, with species of average size (about long). It lived during the Botomian and Toyonian stages of the Lower Cambrian (Olenellus-zone), , in what is currently North America, part of the palaeocontinent Laurentia.

Paradoxides is a genus of large to very large trilobite found throughout the world during the Middle Cambrian period. One record-breaking specimen of Paradoxides davidis, described by John William Salter in 1863, is . The cephalon was semicircular with free cheeks ending in long, narrow, recurved spines. Eyes were crescent shaped providing an almost 360° view, but only in the horizontal plane. Its elongate thorax was composed of 19–21 segments and adorned with longish, recurved pleural spines. Its pygidium was comparatively small. Paradoxides is a characteristic Middle-Cambrian trilobite of th

Eoredlichia is an extinct genus of trilobite of average to large size (up to long, or when including the spine on the ninth thorax segment pointing horizontally to the back, that itself equals the main body length). It lived during the early Cambrian (late Atdabanian) in the Chengjiang fauna of Yunnan, China, and in Australia and Thailand. Eoredlichia is compounded of the Greek (eos, dawn) and Redlichia, a later but related genus, so it means "early Redlichia". The species epithet intermedia means intermediate, indicating it is morphologically intermediate between other species. Eofallotaspis

Balcoracania dailyi is a small (typically about ) trilobite of the family Emuellidae. Its fossils have been found in south Australia and Antarctica.

Emuella is a genus of Cambrian trilobites of the family Emuellidae. Its fossils have been found in South Australia.

Xystridura is a genus of redlichiid trilobite described originally from the Middle Cambrian (Miaolingian) strata of Queensland, Australia. The genus ranges upwards from Ordian into Florian Stages in terms of Australian Cambrian stratigraphic nomenclature.

Nevadia is an extinct genus of redlichiid trilobites, with species of average size (about long). It lived during the Atdabanian stage, which lasted from 530 to 524 million years ago, in what are today Western Canada, the Western United States, and Mexico.
