Marrella splendens Arthropod Image

 

This image created by Doctor Elvira Wood and published in 1920 in The Appendages, Anatomy, and Relationships of Trilobites by Percy E. Raymond. It is of a Marrella splendens (Walcott, 1912) arthropod. Charles Doolittle Walcott collected it from the Burgess Shale of British Columbia, Canada in 1909. He described it as a "lace crab". It turns out it is not a trilobite or a crab. The creature lived in the Cambrian Period.

This image is not correct as you will see if go to the Wikipedia entry below to see more modern interpretations of what this animal looked like. Dr. Raymond was directing Dr. Wood how to illustrate this fossil. He writes on page 116, "The accompanying restoration of the ventral surface of Marrella is a tentative one, based on Doctor Walcott's description and figures. ... The restoration is therefore subject to revision as the species becomes better known."
