New data on Kansaignathus sogdianus, a dromaeosaurid theropod from the Upper Cretaceous of Tajikistan

Isolated sacrum fragments, manual ungual phalanges, and a third metatarsal from the Upper Cretaceous (Santonian) Yalovach Formation at the Kansai locality in Tajikistan, show similarities to those elements in various dromaeosaurid theropods and are referred to Kansaignathus sogdianus, previously described on the basis of a dentary from the same locality. The phylogenetic analysis incorporating the new characters from these elements confirms phylogenetic position of Kansaignathus as the basalmost Asiatic velociraptorine. It is also the oldest known member of this clade in Asia and worldwide.
