Skeletal remains of dromaeosaurid theropods are uncommon in the richly
fossiliferous continental strata of the Upper Cretaceous (Turonian)
Bissekty Formation of the Kyzylkum Desert in Uzbekistan. The
phylogenetic position of the first published specimen, a partial
braincase designated as the holotype of Itemirus medullaris Kurzanov,
1976, has long been contentious. Our examination of the specimen
supports its attribution to Dromaeosauridae. Additional, mostly
well-preserved dromaeosaurid skeletal remains from the Bissekty
Formation include cranial bones, teeth, vertebrae, and some podial
elements. They are tentatively referred to the same taxon, Itemirus
medullaris, and establish the presence of dromaeosaurid paravians in
present-day Central Asia during the Turonian.
