Chilantaisaurus

Chilantaisaurus ("Ch'i-lan-t'ai lizard") is a genus of theropod dinosaur, possibly a neovenatorid or basal coelurosaur, from the late Cretaceous Ulansuhai Formation of China (Turonian stage, about 92 million years ago). The type species, C. tashuikouensis, was described by Hu in 1964. Chilantaisaurus was a large theropod, estimated as weighing between 2.5 metric tons (2.8 short tons)[1] and 4 metric tons (4.4 short tons).[2] In 2010, Brusatte et al. estimated it to weigh 6,000 kilograms (13,000 lb), based on femur length measurements.[3] It is estimated to be around 11 m (36 ft) to 13 m (43 ft) long.
