趣味知識

Unquillosaurus is only known from a single left pubis bone, which is 51.4 centimeters (1 foot 8.2 inches) long.1

Scientists disagree on what type of dinosaur Unquillosaurus was. Some think it was a carcharodontosaurid, others a maniraptoran, and some even think it might be a bird relative.1

The pubis bone of Unquillosaurus points backward, a feature seen in bird-like dinosaurs called maniraptorans.1

Unquillosaurus lived during the Maastrichtian age, about 72 million years ago.1

The name Unquillosaurus comes from the Unquillo River in Argentina, where the fossil was found.1

Unquillosaurus was one of the largest known maniraptorans, a group that includes birds and their closest dinosaur relatives.2

?How big was Unquillosaurus?
