Dale Russell
In his review of Canadian ornithomimids, Dale Russell made "S. brevitertius" the type species of a new genus, Dromiceiomimus, meaning "emu mimic" from the old generic name for the emu, "Dromiceius". Russell also synonymized "Struthiomimus ingens" with "Dromiceimimus brevitertius". He renamed "Ornithomimus samueli" into a second "Dromiceiomimus" species: "Dromiceiomimus samueli". "Dromiceiomimus" was distinguished from "Ornithomimus edmontonicus" on the basis of the following characters: humerus shorter than scapula; ulna ~70% of femoral length; preacetabular process, tibia, metatarsus and pedal digit III longer compared to femur.
