Description

I love these four, but don't ask me the why because I do not know, I just know that I know their respective descriptions practically by heart. <3 xD
Velociraptorinae: the less inclusive clade containing Velociraptor mongoliensis but not Dromaeosaurus albertensis nor Saurornitholestes langstoni, nor Unenlagia comahuensis nor Microraptor zhaoianus. Now, I am convinced that this definition can be traced back for certain only four taxa (Linheraptor exquisitus, Tsaagan mangas, "Velociraptor osmolskae" and, obviously, Velociraptor mongoliensis). In many phylogenetic analysis, Tsaagan appears a much more basal dromaeosaurid, but after the description of Linheraptor the family relationship among these four species is evident, given their endemism and their restricted paleo-geographical distribution.
Then, why I put the quotation marks to V. osmolskae? Because I think that it is in some ways more similar to Tsaagan than to Velociraptor mongoliensis, so I don't see the reason for this generic attribution. "Velociraptor" osmolskae could also represent a form of sexual dimorphism of Tsaagan or Velociraptor mongoliensis, or it could be an entirely new genus. I don't know, it's a very fragmentary specimen (only a maxilla, so you can understand...)
So, about a year ago I made a sketch in pencil about these four taxa (you can find it here: theropoda.blogspot.it/p/paleoa…. But as you can easily understand, this sketch now disgusts me. First, due to the issue of the extension of the integument, then for the hollow fenestrae, and if we want also for the lack of aesthetics. So I just remade it in a better, colored and scaled version.

PS: Luanchuanraptor, Adasaurus and Itemirus are possible velociraptorines, but I did not prefer to include them in this drawing because their systematic is not yet clear (Luanchuanraptor is poorly described, Itemirus is too incomplete, and Adasaurus is a mixture of homoplasyes among unenlagiines, velociraptorines and dromaeosaurines).

Archeroraptor is also one.
