Whittington's analysis did not cover Opabinia? media: Walcott's specimens of this species could not be identified in his collection.[3] In 1960 Russian paleontologists described specimens they found in the Norilsky region of Siberia and labelled Opabinia norilica,[14] but these fossils were poorly preserved, and Whittington did not feel they provided enough information to be classified as members of the genus Opabinia.[2]
