Redlichia
''Redlichia'' is a genus of redlichiida, 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, South Central Siberia, southern Siberia, and Antarctica, and from Middle Cambrian (Ordian)-aged marine strata of Australia. Description ''Redlichia'' has a rather flat and thinly calcified Anatomical terms of location#Dorsal and ventral, dorsal exoskeleton of inverted egg-shaped outline, about 1½× longer than wide, measured across the base of the genal spines and disregarding the spine on the 11th segment of the articulated middle part of the body (or Trilobite#Thorax, thorax). The headshield (or Trilobite#Cephalon, cephalon) is semicircular, about ⅓× as long as the body, with clear genal spines that are a smooth continuation of the border, that extend backward and outward and curving to be near pa ...

Botomian
Cambrian Stage 4 is the still unnamed fourth stage of the Cambrian and the upper stage of Cambrian Series 2. It follows Cambrian Stage 3 and lies below the Wuliuan. The lower boundary has not been formally defined by the International Commission on Stratigraphy. One proposal is the first appearance of two trilobite genera, '' Olenellus'' or '' Redlichia''. Another proposal is the first appearance of the trilobite species '' Arthricocephalus chauveaui''. Both proposals will set the lower boundary close to million years ago. The upper boundary corresponds to the beginning of the Wuliuan. Naming The International Commission on Stratigraphy The International Commission on Stratigraphy (ICS), sometimes unofficially referred to as the International Stratigraphic Commission, is a daughter or major subcommittee grade scientific organization that concerns itself with stratigraphy, strati ... has not named the fourth stage of the Cambrian yet.
