Redlichiida, Suborder Redlichiina, Superfamily Redlichioidea, Family Redlichiidae
Time: Early Cambrian (~525 million years ago)
Site: Changjiang Maotianshan Shales - Quiongzhusi Section, Yu’anshan
Member, Heilinpu Formation, Caijiachong Valley, Yunnan Province, China
trilobite is a member of the Order Redlichiida, Family Redlichiidae
from the Early Cambrian Heilinpu Formation deposits of Caijiachong
Valley, Yunnan Province, China, known as Wutingaspis tingi.
Redlichioids of this type are considered by Richard Fortey to be
the sister group to all of the “higher” (non-Olenelloid)
trilobites. This trilobite is among the so called Chengjiang Biota
that provides the most important lens for study of the Cambrian
Explosion, and is some 5-10 million years younger than the Burgess
Shale fauna. Several fragments of a much larger Redlichiid trilobite
can be seen on both sides of the plate.
