Ondogurvel

Ondogurvel (meaning "egg lizard") is a genus of alvarezsaurid dinosaur from the Late Cretaceous (Campanian) Barun Goyot Formation in southern Mongolia.

The specific name, "alifanovi" honors the late Russian paleontologist Vladimir Alifanov who found the holotype specimen (PIN 5838/1) in 1999.

The describing paper also proposes that the "drastic difference in the morphology of the carpometacarpus [across Parvicursorinae] may suggest a deep divergence between the parvicursorine lineages represented by [Dzharaonyx] – Linhenykus and Mononykus – Ondogurvel".

Phylogeny after Averianov & Lopatin (2022):[1] Alvarezsaurus Achillesaurus Albertonykus Qiupanykus Nemegtonykus Linhenykus Ceratonykus Parvicursor Mononykus Shuvuuia Xixianykus Albinykus Ondogurvel Nemegtomaia, an oviraptorosaur, is also known from the Nemegt locality of the Mongolian Barun Goyot Formation.

[3] Other localities from the formation have yielded dinosaurs including other alvarezsaurids (Ceratonykus,[4] Khulsanurus,[5] and Parvicursor[6]), as well as dromaeosaurs (Hulsanpes,[7] Kuru,[8] and Shri[9]), oviraptorosaurs (Conchoraptor and Heyuannia),[10] a sauropod (Quaesitosaurus),[11] ceratopsians (Bagaceratops and Breviceratops),[12] a pachycephalosaur (Tylocephale),[13] and ankylosaurs (Saichania,[14] Tarchia,[15] and Zaraapelta[16]).
