120 million to 115 million years ago
The type species of *Yellow River Giantsaurus*, *Liujiaxia Yellow River Giantsaurus*, was discovered in Lintao, Gansu Province. The fossil is incomplete, and it weighed 20 tons. In 2006, more than 30 dinosaur fossil sites were discovered in an area of tens of square kilometers in Santun-Liudian, Ruyang County, Henan Province. One incomplete dinosaur fossil, named *Ruyang Yellow River Giantsaurus*, was 18 meters long, with a single toe measuring 20 centimeters. Its forelimbs were relatively long. *Ruyang Yellow River Giantsaurus* was 6 meters tall, with a shoulder width of 3 meters; its hip height was 5.1 meters, and its hip width was 2.8 meters. It was even larger than *Liujiaxia Yellow River Giantsaurus*, weighing 30-40 tons.

5. Luanchuan Dragoon
80 million years ago
*Luanchuanraptor* is a genus of large dromaeosaurid dinosaur discovered in central China, dating to the Early Late Cretaceous. It measured 2.6-3 meters in length and 1.2 meters in height.

These include four teeth, a frontal bone, a cervical vertebra, one or two dorsal vertebrae, 17 caudal vertebrae, ribs, a zygomatic bone, humerus, phalanges and claws, parts of the scapula and pelvis, and other fragmented bones, all from a medium-sized dromaeosaurid. These fossils, numbered 4HIII-0100, are housed in the Henan Geological Museum. It is the first large dromaeosaurid discovered in Asia, far from northeastern China or the Gobi Desert. The type species is *Luanchuanraptor*, described by researcher Lü Junchang et al. in 2007.
