These dinosaurs, an Allosaurus, Tenontosaurus and Tyrannosaurus, were aged 8, 10, and 18.

Sarah Werning and Andrew Lee, graduate students at the University of California, Berkely, when...

Currie and Xian Zhao in the Shishugou Formation during an expedition to the northwestern Chinese desert in 1987. The type species, S. dongi, honors paleontologist Dong Zhiming. It was described by Currie and Zhao in 1994. A second species, originally named Yangchuanosaurus hepingensis by Gao in 1992, may actually represent a second species of Sinraptor. Whether...

It was discovered in 1869 by Ferdinand Vandiveer Hayden. The original finding was identified by locals as "petrified horse hoofs". It was initially placed in the genus...
