Citipes elegans
Taxonomy
Ornithomimus elegans was named by Parks (1933). Its type specimen is ROM 781, a set of limb elements (Tarsometatarsus), and it is a 3D body fossil. Its type locality is Little Sandhill Creek (ROM), which is in a Campanian terrestrial horizon in the Dinosaur Park Formation of Canada. It is the type species of Leptorhynchos, Citipes.

(2004), Longrich (2008) and Sullivan et al. (2011); it was recombined as Elmisaurus elegans by Currie (1989), Currie (1992), Varricchio (2001) and Currie (2005); it was recombined as Leptorhynchos elegans by Longrich et al.
