A rather small trilobite that grows to less than one inch long, CORDANIA wessmani can easily be identified by the wide brim, high cephalon, and very long and broad genal spines that have many tubercles. It has a small pygidium and small eyes set high on the very inflated Cephalon. The glabella is quite bulbous and inflated.
This trilobite is partially enrolled with the tail section tucked under the trilobite. It can be found in the Bois d’Arc formation in Coal County, Oklahoma.
DID YOU KNOW: Trilobites, an extinct form of arthropod related to insects, crabs, crayfish, and horseshoe crabs, are among the most prevalent invertebrates with hard body parts to appear during the Cambrian Period. These creatures are called trilobite due to the three distinct “lobes” running vertically through the body section.
