Marrella; Marella splendens; 520 Ma; Burgess Shale, BC; Collected by Walcott

“Marrella splendens is the most common animal found in the Burgess Shale near Field, B.C.. Although it was initially described as an “odd” trilobite, Marrella was later assigned a class of its own. Complex morphology suggests it gave rise to shrimp, crab, and barnacles. Recently, Marrella has been proposed as the provincial fossil.“
