Discovery and naming
The holotype of Kansaignathus, 2398/15, consists of a right dentary. It was discovered in the Konsoy locality in the north of the Fergana Valley of Tajikistan in the 1960s. The generic name, Kansaignathus, is derived from "Kansai," the Russian name of the location where the holotype specimen was discovered, and the Greek "gnathos," meaning jaw. The specific name, sogdianus, is derived from Sogdiana, an ancient region in Central Asia. It represents the first non-avian dinosaur described from Tajikistan.[1]
Additional remains from the same formation, consisting of sacrum fragments, manual phalanges and a third metatarsal, were referred to Kansaignathus in 2023.[2]
Classification
