Known locations: Mongolia,‭ ‬Ömnögovi Province‭ ‬-‭ ‬Djadokhta Formation.
Time period: Campanian of the Cretaceous.
Fossil representation: Skull and cervical‭ (‬neck‭) ‬vertebrae and shoulder girdle.

       Originally thought to be another specimen of Velociraptor,‭ ‬a CAT scan in‭ ‬1998‭ ‬revealed that the fossil was of a new though closely related genus.‭ ‬Additional study of Tsaagan has indicated that it is most closely related to Linheraptor.‭ ‬Tsaagan probably lived and hunted like most other small Asian dromaeosaurids,‭ ‬hunting either other small dinosaurs as well as possibly smaller vertebrates such as lizards or even small mammals like Zalambdalestes.
