酷東西

趣味知識

Tsaagan is only the second dromaeosaurid dinosaur ever found in the Djadokhta Formation, after Velociraptor.1

Its name comes from the Mongolian words for 'white' and 'monster'.1

The only known Tsaagan fossil is a well-preserved skull and the first eight neck bones from an adult.2

Tsaagan had a straight, hanging paroccipital process on its skull, which is different from other raptors.1

Scientists used CT scans to study the inside of Tsaagan's skull and brain case.1

Tsaagan lived about 83 to 72 million years ago, during the Campanian age of the Late Cretaceous.4
