In 2004 Viktor S. Tereschhenko referred a juvenile specimen (PIN 4046/11) to "Udanoceratops" aff. "tschizhovi", from the Baga Tariach locality in Dornogovi Province, which Tereschhenko attributed to the Djadokhta Formation. Geological analyses carried out across fossiliferous localities of the Gobi Desert published by Mahito Watabe and team in 2010, indicates that this locality instead correlates best with the Maastrichtian-stage Barun Goyot Formation. The assignment of this specimen, however, has varied since then from "Udanoceratops" sp., to ?"Udanoceratops" sp.
