Taxonomy
Avimimus portentosus was named by Kurzanov (1981). Its type specimen is PIN 3907/1, a partial skeleton, and it is a 3D body fossil. Its type locality is Udan-Sayr (PIN Loc. 3907) [MPE/SMPE], which is in a Campanian terrestrial sandstone/sandstone in the Djadokhta Formation of Mongolia. It was considered monophyletic by Currie (2000).

Diagnosis
Reference | Diagnosis | |
---|---|---|
T. Tsuihiji et al. 2017 | (Cranial Characters) Avimimus portentosus is distinguished from other oviraptorosaurians on the basis of the following autapomorphies: five denticulations along occlusal margin of premaxilla (as proposed by Kurzanov, 1987); posterior margin of fused nasals strongly concave, surrounding large fossae posteriorly bounded by frontals; quadratojugal thin and long, reaching anterior one-third of orbit; and bones of braincase, squamosal, quadrate, quadratojugal, postorbital, and pterygoid co-ossified. | |
G. F. Funston et al. 2018 | Small oviraptorosaurian theropod diagnosed by the following features (autapomorphies indicated by asterisk, plesiomorphies indicated by dagger): premaxilla invaded by antorbital fenestra*; fused neuro- cranium*; low mandible with poorly developed symphyseal shelf†; dorsal vertebrae without lateral pleurocoels*; fused carpometacarpus*; fused tibiotarsus incorporating distal end of fibula*; fused tarsometatarsus lacking first digit and with proximally absent third metatarsal*. |
