Mononykini

Reptilia - Alvarezsauridae

Taxonomy
Mononykinae was named by Chiappe et al. (1998). It was considered monophyletic by Chiappe et al. (1998).

It was synonymized subjectively with Parvicursorinae by Choiniere et al. (2010); it was reranked as the unranked clade Mononykini by Agnolin et al. (2012).

It was assigned to Alvarezsauridae by Chiappe et al. (1998), Chiappe et al. (2002), Suzuki et al. (2002), Martinelli and Vera (2007) and Longrich and Currie (2009); and to Parvicursorinae by Agnolin et al. (2012).

Diagnosis
ReferenceDiagnosis
L. M. Chiappe et al. 1998Mononykinae is phylogenetically defined as the common ancestor of Mononykus, Shuvuuia, and Parvicursor, plus all their descendants.
L. M. Chiappe et al. 2002Alvarezsaurids with supracetabular crest on ilium extending only over the rostral half of the acetabulum; laterally compressed and kidney-shaped proximal end of pubis; absence of femoral posterior trochanter; medial border of tibiotarsus strongly projected proximally; fibula greatly reduced distally, without reaching the proximal tarsals; proximal end of metatarsal III reduced, not reaching the tarsals (arctometatarsalian condition).
