This revelation shines some light on the sexuality of dinosaurs, with reproductive maturity being earlier than researchers previously believed.
Sinraptor, meaning "Chinese thief," is a genus of theropod dinosaur from the Late Jurassic Period. It was discovered by Philip J.

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...
