Corynexochida Trilobites

The members of trilobite Order Corynexochida (pronounced Cory-nex-o-chee-da) comprise a large and morophologically diverse and complex trilobite clade with a biostratigraphy range from the Lower Cambrian to the Middle Devonian. The Corynexochida are divided into three suborders, Corynexochina, Illaenina and Leiostegiina that have distinctly different morphological traits. Cladistic data suggests the widely accepted phylogenetic view that the corynexochids descended from the Redlichiina during the Lower Cambrian. Read more about Corynexochid trilobites.
