Diagnosis
ReferenceDiagnosis
H. Osmolska 1981 (Elmisauridae)Lightly built, medium sized theropods with very thin-walled limb bones. Manus slender, anisotridactyl with long digits; second digit the longest and strongest, with phalanges 1 and 2 equally long; the third digit distinctly thinner than others, unguals laterally compressed and curved, with a dorsoposterior "lip." Pes long and slender, functionally tridactyl and with abbreviated first digit; metatarsal III edged between adjoining metatarsals but anteriorly visible for most of its length; third digit the longest, second and fourth digits subequal in length, unguals recurved.
R. Barsbold 1981Moderately large oviraptorosaurs, the lower jaw of which is elongated and concave in the occlusal part, low adductoral projection, elongated symphysis and narrowed lateral opening.
H.-D. Sues 1997Antorbital fossa on maxilla with pronounced rim. Medial wall of antorbital fossa extensive and without accessory antorbital fenestra. Mandible with long, low, and undivided external mandibular fenestra. Braincase much deeper than long, with distinctly verticalized basicranial region. Otic region with deep but anteroposteriorly narrow lateral depression. Manual digit III longer than digit I and with very slender phalanges. Synsacrum composed of six co-ossified vertebrae with pneumatic foramina. Proximal end of metatarsal III distinctly constricted and pinched between metatarsals II and IV.
