| Suborder Redlichiina
Cephalon: with opisthoparian facial sutures; early forms tend to have tapering, conical glabella with furrows extending far backwards; later forms with glabella expanding forwards to inflated frontal lobe; hypostome conterminant (e.g., Redlichia) or natant (e.g., Dolerolenus), rostral plate narrower than in Olenellina, bound by rostral and connective sutures. Thorax: fulcrate or non-fulcrate, typically with many segments (60+ in an Emmuelid); axis infrequently spine-bearing. Pygidium: typically small, but can be larger and with many segments. Superfamilies: Emuelloidea, Redlichioidea, Paradoxidoidea. Superfamily Redlichioidea |
