Note added in proof
The recent description of the dromaeosaurid Linheraptor (Xu et al.,
2010) from the Gate locality at Bayan Mandahu slightly complicates
our referral of the dromaeosaurid teeth described in this paper (IVPP
V16138) to Velociraptor. Linheraptor is similar in size and gross
morphology to Velociraptor, but the poor condition of the premaxillary
and anterior dentary teeth of the only known specimen of
Linheraptor makes comparisons to IVPP V16138 difficult. In any case,
the abundance of Velociraptor remains at Bayan Mandahu suggests
that this is still the more likely candidate, and uncertainty at this
taxonomic level does not affect our broader inference of a trophic
relationship between dromaeosaurids and basal neoceratopsians
