Cedaria minor (Walcott, 1916)
This trilobite is a member of the family Cedariidae known as Cedaria minor. Cedaria is a small, rather flat trilobite with an oval outline, a headshield and tail shield of approximately the same size, 7 articulating segments in the middle part of the body and spines at the back edges of the head shield that reach halflength of the body. Cedaria lived during the early part of the Upper Cambrian (Dresbachian), and is especially abundant in the Weeks Formation.
