A reassessment of Kelmayisaurus petrolicus, a large theropod dinosaur from the Early Cretaceous of China [PDF]

, 2012
The Early Cretaceous fossil record of large-bodied theropods from Asia is poor, hindering comparison of Asian predatory dinosaur faunas with those from other continents. One of the few large Asian theropod specimens from this interval is a partial skull (
