- Proper aspect of the skeleton is broken, however the remaining is in good situation (no finish of the tail)
- First considered a juvenile Saurornitholestes, after which later considered a brand new Velociraptor species, Velociraptor feinbergi
- Helps present the hyperlink between non-avian dinosaurs and birds
