       Unquillosaurus is a genus of dromaeosaurid dinosaur that lived in South America during the Late Cretaceous.‭ ‬At the time of the genus description‭ (‬and writing here‭)‬,‭ ‬Unquillosaurus is only known from a single pubis bone‭ (‬part of the pelvis‭)‬,‭ ‬and so it is very difficult to infer much detail about this dinosaur.
