Reconstruction of the skeletons of Struthiomimus altus (left) and Ornitholestes hermanni (right). Struthiomimus 1/10, Ornitholestes 1/6 natural size, The Ornitholestes restoration replaces the original restoration by Osborn in 1903 which is very faulty. The Struthiomimus, Amer. Mus. 5339, mount has the distal end of the tail restored from Amer. Mus. 5355; dotted vertebra from Amer. Mus. 5262, In both restorations the pollex is too closely appressed to the other digits, see Fig. 3. in Skeletal Adaptations of Ornitholestes, Struthiomimus, Tyrannosaurus
