The paper also features this tantalizing snippet regarding _Itemirus
medullaris_, from the Bissekty Formation:


"_Itemirus_ has sometimes been classified as a tyrannosauroid
(e.g., Holtz, 2004), but newly collected material indicates that
it is, in fact, referable to Dromaeosauridae (Sues and Averianov,
in preparation)."


It should be noted that _Itemirus_ was found to be a dromaeosaurid (a
velociraptorine, no less) in the phylogenetic analysis of Longrich and
Currie (2009), in their description of _Hesperonychus_.  But the
prospect of new _Itemirus_ material is exciting.
