Belongs within: Trilobita.
The Redlichiina are a group of relatively plesiomorphic trilobites known from the Lower and Middle Cambrian (Harrington et al. 1959). Some members of this group grew very large; the Middle Cambrian North American species Paradoxides davidis was almost two feet long (Prothero 1998). Members of the superfamily Redlichoidea lack an expanded anterior section on the glabella and have long, crescentiform eyes.
Characters (Harrington et al. 1959): Dorsal exoskeleton elongate, subelliptical in outline. Cephalon semicircular to semielliptical, mostly with prominent genal spines; glabella with subparallel sides, narrowing fonvard, or expanding fonvard, generally well segmented; facial sutures opisthoparian; eyes mostly large, tending to be crescentic. Thorax with numerous segments. Pygidium small.
