Diagnosis

Reference	Diagnosis
K. A. v. Zittel 1890	Schädel unbekannt. Vorderbeine kurz. Hand dreizehig. Hinterbeine sehr lang. Astragalus mit langem, aufsteigendem Fortsatz. Von den drei funktionirenden Metatarsalia ist das mittlere (III) proximal verschmälert und durch die verdickten Gelenkenden der beiden anderen ganz nach hinten gedrängt.
R. S. Lull 1924	The relatively small skull, with its large orbit, borne upon very long, slender cervicals, is one of the most characteristic features of this group. Limbs long and slender, with specialized manus, bearing three digits, the elongated claws of which are not strongly curved; pubic bones possessing foot-like symphysis, ischia being curbed; tibia longer than femur; metatarsals elongated and closely appressed, but remainder of foot of moderate size, with short, rather straight unguals; tail long, with distal caudals interlocked by prolonged zygapophyses.
F. v. Huene 1948	Strong, pointed teeth or toothless; large preorbit; 10 cervicals, 13 dorsals, 5 sacrals; manus with 3 long fingers; pubis a little shorter than femur, with shoe-like process; tibia a little shorter than femur; astragalus with high ascending process; 3 middle toes long, bird-like, I missing, V rudimentary. Cretaceous.
R. Barsbold 1981	Progressive ornithomimosaurs with elongated ilia (longer than the pubis) and metatarsus, proximally highly compressed third metatarsal element and without the first toe (pollex). Pleurocoels are present.
